An effective polyaniline-based electrochromic device was successfully achieved using the enzyme-mediated poly (gallic acid) as a polyaniline polymerization template. Poly (gallic acid) proved non-toxic upon the conducted cytotoxicity assays. Thermogr

The semiconducting and non-toxic enzymatic polygallic acid (PGAL) produces water dispersible poly(3,4-ethylenedioxythiophene) (PEDOT-PGAL) and polyaniline (PANI-PGAL). The results indicate that PGAL is a template for the model polymers, and thereby,
