Composition‐dependent electrical and dielectric properties of polyaniline/graphene composites produced by in situ polymerization technique
TLDR
In this article, two types of Pani/graphene composites were prepared, composite-1: where graphite powder as procured is used for preparation of composites and composite-2: graphite powders are subjected ball milling for further reduction of graphite particles size and then used for preparing composites.Abstract:
Polyaniline (Pani)/Graphene nanocomposites with different compositions were prepared by in situ polymerization of aniline in presence of graphene oxide. Two types of Pani/graphene composites were prepared, composite-1: where graphite powder as procured is used for preparation of composites, composite-2: graphite powder is subjected ball milling for further reduction of graphite particles size and then used for preparation of composites. DC and AC resistivity of these composites have been found to be composition dependent. In fact composite-2 exhibit lower resistivity compared to composite-1 at same composition. However, both composites show frequency-independent AC resistivity but frequency-dependent dielectric constant and loss. POLYM. COMPOS. 36:445–453, 2015. © 2014 Society of Plastics Engineersread more
