abstract = "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., 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.",
