Dielectric and electrical properties investigation of polyamide/polyaniline composite films

Abstract

Surface conductive composites for antistatic purposes consisting of polyamide 6 (PA‐6) polymer films as a matrix containing conductive polyaniline (PANI) particles were chemically elaborated at room temperature by in situ polymerization of aniline inside the matrix. These kind of Polyamide/PANI composites were investigated regarding to their microstuctural and electrical properties. The surface conductivity was characterized using the potential decay technique. The results were correlated with scanning electron microscopic images data concerning PANI particles dispersion in these antistatic polymer films (ASPF). The enhanced surface conductivity was due to percolation of the PANI phase in the surface layer of PA‐6 films. It has been shown by X ray spectra that the crystallinity of the films is also enhanced.
