Properties of Polyaniline Blends

폴리아닐린 블렌드의 물성

Polyaniline/polystyrene conducting blends were prepared and measured with the mechanical properties such as tensile strength and elongation and the electrcal properties such as surface resistance, electrical conductivity and dielectric loss tangent. The percolation threshold concentration of blends was 5phr of polyaniline and the morphology of blends was setting colser to that of polyaniline at higher concentration. The dielectric loss increased up to $10^5$ at the 50 % of polyaniline and was much influenced by frequency than temperature at higher concentration of polyaniline.
