The results of experimental studies of the properties of composite materials based on Poly(lactide-co-glycolide) (PLGA) matrix 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 0.4-7.2 vol. %. The samples were prepared by hot moulding injection at 140°C. Influence of morphology on the conductivity and percolation threshold of the composites was 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 was 2.72 vol.%, which is about three times lower than the one stated in the literature for similar composites. This property is ascribed to differe...nt morphology of filler used in investigation.
