摘要

Conductive polymers are of great interest for high-performance applications. Integrating electrical conductivity into biobased polymers presents both a scientific challenge and a promising opportunity to develop sustainable and environmentally friendly materials. Polyaniline was grafted onto chitin whiskers, and the grafting degree and conductivity were tuned by varying the mole ratio of partially deacetylated chitin units to chitosan units. This is the first report on the conductivity of neat polyaniline-grafted chitin whiskers from a compressed pellet. The optimum grafting degree was 59%, and the highest conductivity achieved was 1.71 × 10–4 S/cm.
