Complementary electrochromic devices of PANI and PEDOT using the enzymatic poly(gallic acid)

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, the complexes are processable by spray coating to produce flexible electrochromic devices (ECDs). The materials were characterized by infrared spectroscopy, thermogravimetric analysis, and...
