AB  - Composite materials nowdays are increasing industrial applications worldwide. Composites based on polymers with conductive fillers are getting wider research focus primarily because of their growing importance from the point of application in: electronics, medicine, industry and so on. Besides mentioned above, these composites have found application as contact conductive materials, electromagnetic and radio wave shields, photothermal optical recorders, electronic noses sensitive to certain chemicals, as well as economically acceptable catalysts. The results of experimental studies of the properties of composite materials based on lignocellulosic (LC) and Poly(methyl methacrylate) (PMMA) matrices filled with electrolytic copper are presented in this chapter. Volume fractions of metal fillers in tested composite materials were varied in the range of 1.6–30% (v/v), and the samples were prepared both by compression – cold pressing and hot moulding. The results have shown that shape and morphology of the copper powder, and filler at all, play a significant role in the phenomenon of electrical conductivity of the prepared samples, as well as on the appearance of percolation threshold. The particles with highly developed free surface areas like dendrites, having highly branched structures (such as electrolitically obtained copper powder particles) can much easier form interparticle contacts at lower filler volume fractions than the particles with more regular surface. Layered electrical conductivity throughout the entire sample volume was observed, whereby the resistance of the inner layers was the leading processes of the entire composite resistance. It can be seen that the resistance has increased due to increased contribution of the polymer matrix inner surface area as the frequency decreased. Conductivity measurements have shown typical S-shaped dependence with the percolation transition from nonconductive to conductive region. For all the processing pressures, the percolation threshold for smaller particle sizes was lower than for larger ones. This difference has increased with the increase of processing pressure. A significant increase in the electrical conductivity have been observed when the content of conductive filler in the composites reached the percolation threshold. The effect of particle packaging and pronounced interparticle contact with smaller, highly porous and dendritic particles with large specific surface areas, led to a “shift” of percolation threshold to lower values of filler volume fractions. It was noticed that this transition occurred at lower values of filler content than it was stated in the literature, which is due to the use of fillers with large specific surface areas.

AB  - This manuscript presents the results of investigating the properties of composite materials having poly(lactide-co-glycolide) (PLGA) matrix filled with electrolytically produced copper powder whose particles have a highly developed branched structure. The volume fraction of the copper powder used as a filler for the preparation of the composite was varied from 0.4 to 7.2 vol. %. The samples were prepared at 140 °C by hot molding injection. The effect of the morphology of electrolytically obtained copper powder on the appearance of the percolation threshold and on the conductivity of the composites was studied. Characterization included impedance spectroscopy (IS) measurement of electric conductivity and scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and Fourier-transform Infrared Spectroscopy (FTIR) morphological analysis. Electric conductive pathways were formed throughout the entire volume of the composites, where their formation was purely stochastic in all the dimensions. The percolation threshold was 2.72 vol.%, which is significantly lower than the one stated in the literature for similar composites, since these kind of composites are investigated for the first time. This property can be attributed to the use of a filler of different, diverse morphologies.

AB  - The results of experimental studies of the properties of composite materials based on Poly (lactic
acid) (PLA) and Poly (3-hydroxybutyrate) (PHB) matrices filled with electrolytic copper powder,
having very high dendritic structure, are presented in this manuscript. Copper powder volume
fractions used as filler in all prepared composites were varied in the range of 0.5-6.0 %(v/v). The
samples were prepared by hot molding injection at 170°C. Influence of particle size and morphology,
as well as influence of matrix type on the conductivity and percolation threshold of the composites
were examined and characterization included: Electrical conductivity measurements using
Impedance Spectroscopy (IS), Scanning Electron Microscopy (SEM), Energy-dispersive X-ray
spectroscopy (EDS) and Fourier-transform Infrared Spectroscopy (FTIR). Presence of three
dimensional conductive pathways was confirmed. The obtained percolation threshold of 2.83 %(v/v)
for PLA and 3.13 %(v/v) for PHB composites was measured, which is about three times lower than
the one stated in the literature for similar composites. This property is ascribed to different
morphology of filler used in investigation.

Volume fractions of the copper powder used as filler in all prepared composites were varied in the range 0.5-6.0 vol.%. Samples were prepared by hot moulding injection at 170 degrees C. Influence of particle size and morphology, as well as the influence of matrix type on conductivity and percolation threshold of the obtained composites were examined. Characterization included: electrical conductivity measurements using AC impedance spectroscopy (IS), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and Fourier-transform Infrared spectroscopy (FTIR). Presence of three-dimensional conductive pathways was confirmed. The obtained percolation thresholds of 2.83 vol.% for PLLA and 3.13 vol.% for PHB composites were measured, which is about three times lower than the ones stated in the literature for similar composites. This property is ascribed to different morphologies of the filler used in the present investigation.",

AB  - Hydroxyapatite (HAp) is the most suitable biocompatible material for bone implant coatings. However, its brittleness is a major obstacle, and that is why, recently, research focused on creating composites. In this study, a novel in situ synthesis of HAp coating on titanium was presented. HAp was anaphoretically deposited from alkaline-ethanol suspension in one step process. Morphology of the coating was investigated by optical microscopy, while deposited HAp was characterized using ATR-FTIR. It was concluded that HAp has excellent coverage of the surface without delamination. The obtained coating can be good material for bone implants due to solving HAp brittleness.

AB  - In this manuscript the results of experimental studies of the properties of composite materials based on lignocellulosic matrix (LC) filled with electrolytic copper powder and chemically obtained silver powder are presented. Volume fractions of metal fillers in the composite materials in tested samples were varied in the range of 1.6-30% (v/v), and the samples were prepared by compression - cold pressing. Characterization included examination of the influence of particle size and morphology on the conductivity and percolation threshold of the composites using variety of testing techniques: SEM, TGA, DSC, particle size distribution and conductivity measurements. Thermal analysis of the prepared composites showed the improvement of the thermal characteristics of the composites. This was due to the presence of the metallic fillers which are very good thermal conductors, hence accumulating the emitted heat during TGA measurements primary to lignocellulosic matrix. On the other hand, there is no difference in the response with different metallic fillers and particles with different morphologies. Glass transition temperature is improved by 20ºC for all the composites.

Udeo metalnih punilaca u kompozitnim materijalima u ispitnim uzorcima variran je u opsegu od 1.6-30% (v/v), a uzorci su pripremljeni hladnim presovanjem - kompaktiranjem pri različitim pritiscima. Karakterizacija i ispitivanje uticaja veličine i morfologije čestica na termijske karakteristike dobijenih kompozita. je uključivala različite tehnike ispitivanja: SEM, TGA, DSC, raspodelu veličina čestica i merenja provodnosti. Rezultati termijske analize pripremljenih kompozita pokazuju poboljšanje termalnih karakteristika samih kompozita usled prisustva metalnih punilaca koji su izrazito dobari termički provodnici, tako da se emitovana količina toplote tokom TGA merenja prvobitno akumulira u česticama punioca, pa tek potom dolazi do promene u samoj lignocelulozi. Sa druge strane, nema razlike u odgovoru kompozita sa različitim veličinama i vrstama čestica. Temperatura prelaska u staklasto stanje lignoceluloze kod svih pripremljenih kompozita je povećana za oko 20ºC.

abstract = "In this manuscript the results of experimental studies of the properties of composite materials based on lignocellulosic matrix (LC) filled with electrolytic copper powder and chemically obtained silver powder are presented. Volume fractions of metal fillers in the composite materials in tested samples were varied in the range of 1.6-30% (v/v), and the samples were prepared by compression - cold pressing. Characterization included examination of the influence of particle size and morphology on the conductivity and percolation threshold of the composites using variety of testing techniques: SEM, TGA, DSC, particle size distribution and conductivity measurements. Thermal analysis of the prepared composites showed the improvement of the thermal characteristics of the composites. This was due to the presence of the metallic fillers which are very good thermal conductors, hence accumulating the emitted heat during TGA measurements primary to lignocellulosic matrix. On the other hand, there is no difference in the response with different metallic fillers and particles with different morphologies. Glass transition temperature is improved by 20ºC for all the composites., U ovom radu su prikazani eksperimentalni rezultati istraživanja termijskih svojstava kompozitnih materijala na bazi lignocelulozne matrice (LC) punjenih elektrolitičkim bakarnim prahom i hemijski dobijenim srebrnim prahom. Udeo metalnih punilaca u kompozitnim materijalima u ispitnim uzorcima variran je u opsegu od 1.6-30% (v/v), a uzorci su pripremljeni hladnim presovanjem - kompaktiranjem pri različitim pritiscima. Karakterizacija i ispitivanje uticaja veličine i morfologije čestica na termijske karakteristike dobijenih kompozita. je uključivala različite tehnike ispitivanja: SEM, TGA, DSC, raspodelu veličina čestica i merenja provodnosti. Rezultati termijske analize pripremljenih kompozita pokazuju poboljšanje termalnih karakteristika samih kompozita usled prisustva metalnih punilaca koji su izrazito dobari termički provodnici, tako da se emitovana količina toplote tokom TGA merenja prvobitno akumulira u česticama punioca, pa tek potom dolazi do promene u samoj lignocelulozi.
