Biopolymer and conducting polymer based nanoparticles for electrorheological fluids

In recent years, environmentally friendly and enzymatically biodegradable biopolymers have attracted the attention of researchers. The advantage of these materials is decomposition naturally in nature [1]. Biopolymers are playing important role in nanotechnology. Chitosan is one of the well-known biopolymers and is produced by deacetylation of chitin. The degree of deacetylation directly correlates with its properties. Chitosan has great potential for the biocompatible material production due to its biodegradability, biocompatibility and antimicrobial activity. Also, chitosan is an antibacterial agent and its positively charged chains destroy the negatively charged bacterial cell walls [2].
