AB  - U ovom radu su prikazani eksperimentalni rezultati ispitivanja kompozitnih materijala na bazi lignoceluloznih (LC) i polimetilmetakrilatnih (PMMA) matrica punjenih bakarnim prahom. Zapreminski udeli metalnog punioca su varirani u opsegu od 0.5-29.8% (v/v), a uzorci su pripremljeni hladnim presovanjem i izlivanjem u kalup. Karakterizacija je uključivala ispitivanje uticaja veličine čestica i morfologije na provodnost i perkolacioni prag kompozita koristeći različite tehnike ispitivanja: SEM, TGA, AFM. Termalna analiza pripremljenih kompozita je pokazala poboljšanje termičkih svojstava kompozita u odnosu na čiste polimere. Ovo poboljšanje se javlja usled prisustva metalnog punioca, koji je jako dobar termički provodnik, te se toplota emitovana tokom TGA merenja prvenstveno akumulira u puniocu, pa tek onda u polimernoj matrici, bila ona LC ili PMMA. Prisustvo trodimenzionalnih provodnih puteva je takođe potvrđeno.
AB  - In this manuscript the results of experimental studies of the properties of composite materials based on lignocellulosic (LC) and poly(methylmethacrylate) matrices filled with electrolytic copper powder are presented. Volume fractions of metal fillers in composite materials and tested samples were varied in the range of 0.5-29.8% (v/v), and the samples were prepared by compression and molding. Characterization included examination of the conductivity and percolation threshold of the composites using a variety of testing techniques: SEM, TGA, AFM. 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 heat emitted during TGA measurements primary to matrix, whether it was lignocellulosic or PMMA. presence of three dimensional conductive pathways was confirmed.

AB  - The relationship between the light-reflecting property generally referred to as the brightness, and structure of electrodeposits has been the subject of many investigations. These studies have led to two theories. One theory states that electrodeposits are bright if their microstructure consist of crystallites smaller than the wavelength of visible light, i.e., smaller than 0.4 micrometers. At the same time, for the surface to be bright, a roughness of less than 0.15 micrometers and 0.025 micrometers is required. The second theory states that the more oriented the grain structure, the brighter the deposit, the bnghtnes being dependent on the degree to which the morphological components of the surface of electrodeposits are in plane. On the other hand, it has been found that a major fraction of mirror-bright (Ni) metal electrodeposits exhibit no preferred orientation. Hence, both theories do not hold. The conditions which must be fulfilled in order for the metal surfaces to exhibit mirror brightness have not been classified and systematized yet. Progress in the investigation of the structure of bright metal surfaces has accelerated recently, thank to the development of the Scanning Tunnelling Microscopy (STM) and Atomic Force Microscopy (AFM) techniques. It has been shown by these techniques that the reason of the mirror brightness of electropolished copper surfaces might be that large parts of the surface consists of small, flat and mutually parallel metal crystals, which exhibit smootthness on the atomic level. For this reason, it was considered necesarry to examine whether this conclusion about the structural features of electropolished mirror bright metal surfaces is also valid and for bright metal coatings obtained by electrodeposition.

AB  - Mirror brightness of metal surfaces can be associated with the high degree of mirror reflection which approaches very nearly the ideal reflectance of the same metal. The samples of steel and copper are processed by electrochemical polisher in corresponding electrolytes for electrochemical polishing. On previously mechanically, and further electrochemically polished samples surface roughness and surface reflection were measured. The effect of decreasing surface roughness of electrochemically polished samples was shown compared to only mechanical polished samples. Following the changes in the relation of the mirror, the total and the diffuse reflection, it is confirmed that it came to significant increase of brightness of the surface polished by electrochemical method, compared to initial surface, both for steel samples and for copper samples.
AB  - Ogledalski sjaj metalnih površina se može povezati sa visokim stepenom ogledalske refleksije koji se približava idealnoj refleksivnosti istog metala. Uzorci čelika i bakra su podvrgnuti elektrohemijskom glačanju u odgovarajućim elektrolitima za elektrohemijsko glačanje. Na prethodno mehanički, a zatim elektrohemijskim glačanim uzorcima merena je hrapavost površine i refleksija svetlosti. Pokazan je uticaj smanjenja površinske hrapavosti elektrohemijski glačanih uzoraka u odnosu na samo mehanički glačane uzorke. Prateći promene odnosa ogledalske, ukupne i difuzne refleksije potvrđeno je da je došlo do značajnog povećanja sjaja površine glačane elektrohemijskim putem u odnosu na polaznu površinu, kako za uzorke čelika tako i za uzorke bakra.

AB  - The properties which determine whether the metal surface is mirror bright are precisely determined by STM investigations. Mirror brightness of metal surfaces can be associated with the high degree of mirror reflection which approaches very nearly the ideal reflectance of the same metal. Mirror brightness of the copper coatings and the copper surfaces polished both mechanically and electrochemically was determined by flat and mutually parallel parts of the surface which are smooth on the atomic level and which point out towards layer structure of these surfaces. Mirror bright metal surfaces can be obtained only by electrochemical polishing or electrochemical deposition in the presence of brightening addition agents. It was shown that mirror brightness of metal surfaces can be associated with the high degree of mirror reflection which approaches very nearly the ideal reflectance of the same metal, with the small degree of diffuse reflection.
