Electrochromic organic materials copolymers

Owing to the intense research into PANI, one can ensure that new materials will be created in the coming months and years composites, co-polymers, (graft copolymers of PANI and nitrilic rubber [104]), PANI self-doped with organic acids, and so on. It was announced very recently that PANI electropolymerized in cam-phor.sulfonic acid (CSA) presented electrochromic properties analogous to PANI electropolymerized in common acids [105], In fact, it seems that PANl-CSA presents noteworthy stability during electrochromic cyclings [58]. 

Polythiophenes with P-alkyl substituents including more than three carbon atoms are commonly soluble in organic solvents. Recently, electrochromic polymers such as poly(thiophene-3-acetic acid) and its copolymer with polythiophene were prepared. The electrochromic properties of these materials were studied by observing a color change from red to black during the potential sweep with a stability for 264 cycles, establishing a high electrochromic efficiency of up to 242 cm C at 750 nm [65],...
