This article is concerned with synthesis and characterization of electroconductive composite materials prepared by hot molding of mixtures of PMMA and electrochemically deposited copper powder and investigation of the influence of particle morphology on conductivity and percolation threshold of obtained composites and thermal characteristics. Electrodeposited copper powder content was varied from 0.5-8.8 vol%. Analysis of the most significant properties of individual components and prepared composites AFM and TGA analysis. The significant increase of the electrical conductivity can be observed as the copper powder content reaches the percolation threshold at 2.98 vol%. In the investigated range of electrodeposited copper powder concentrations the increase of the electrical conductivity of composites is as much as sixteen orders of magnitude.
