Some aspects of preparation methods and properties of polyaniline blends and composites with organic polymers
TL;DR: In this paper, generalized approaches for the preparation of polyaniline materials are reviewed, focusing on features that determine properties of the final composites/blends, and two distinct groups of synthetic methods based on aniline polymerization either (1) in the presence of or inside a matrix polymer or (2) the blending of a previously prepared PANI with a matrix polymers.
