Structural and Morphological Characteristics of Polyethylene Composites with Different Conductive Fillers


Abstract:
Structural and morphological features of compositions based on LDPE which contains different types of fillers for creation of conductive polymer products are presented in this article. Different types of fine metallic fillers, such as Al, Br, Cu, and flake-like graphite were used in this work. Comparative assessment of morphometric characteristics of particulate fillers: area, perimeter, equivalent diameter, shape factor and their distribution on these indicators were performed by methods of optical microscopy and image analysis. Composite films based on LDPE, containing 5% vol. with different types of conductive fillers were obtained by pressing method. It was found that the nature of the filler quantitatively influences on the uniformity of distribution of its particles in composite films. The most structural homogeneity was observed in PE-Gr and PE-Cu composites, while the least - in PE-Br composite. It was shown that the increasing of average particle anisotropy for investigated fillers reduces their heterogeneity of distribution in composite films.
