“…This study aimed to construct an ESC device with an integrated electrochromic layer (i.e., CPP composite hydrogel), providing a new methodology for the facile and rapid construction of ESC devices. It should be noted that the present ESC device showed a much lower transmittance change than that of the reported ESCs (up to 40%) [ 31 ]. This was mainly caused by the huge difference in the thickness of the electrochromic layer.…”

“…PANI has been considered as the second most-used conductive polymer in biomedical fields because of the beneficial features such as different structural forms, inexpensiveness, high stability in various environmental conditions, and the capability to electrically shift between resistive and conductive states by applying doping/dedoping procedure. PANI is suitable in electrochromic and supercapacitor, [68] biosensor, [69] NPs, [70] and drug delivery applications. [71] PANI is a homopolymer containing benzenoid or quinonoid or both of them in its structure with various ratio.…”
