The black-to-transmissive electrochromic polymer has significant value with practical applications. Integration of electrochromic and supercapacitor bifunctional materials can indicate its capacitor level by visual color change in real-time. In this paper, based on three EDOT derivative monomers were associated to phenanthrocarbazole/benzotriazole/benzothiadiazole, M1, M2 and M3, a novel ternary random copolymer film was successfully prepared by electrochem. copolymerization Since the corresponding homopolymers of three monomers are red, green and blue in the neutral state resp., and their oxidation states are all transparent, therefore the obtained ternary random copolymer films show the black-to-transmissive electrochromic behavior. The copolymer film pCo-2 was prepared via electrochem. copolymerization with suitable monomers feed ratio (1: 1.5: 1 of M1: M2: M3). Benefit from ternary random electrochem. copolymerization, the pCo-2 copolymer displays excellent electrochromic-supercapacitor properties among the similar bifunctional materials, with fast response time, high optical contrast, good cycling stability and large area (volume) specific capacitance. The electrochromic supercapacitor device based on pCo-2//PEDOT can make an LCD run continuously. This work provides an available general approach to realizing black-to-transmissive electrochromism towards electrochromic-supercapacitor bifunctional applications. In the experiment, the researchers used many compounds, for example, 1-Bromopyrrolidine-2,5-dione (cas: 128-08-5Recommanded Product: 128-08-5).
1-Bromopyrrolidine-2,5-dione (cas: 128-08-5) belongs to organobromine compounds. Organo bromine compounds are versatile compounds and are widely used in diverse fields. Organo bromine derivatives are used in the dye sector, as an indicator in analytical chemistry (Bromothymol blue is a popular indicator). When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.Recommanded Product: 128-08-5
