In the improvement of stability and lifetime of bistable electrochromic (EC) materials, the microcapsule technique was used to protect the EC materials in a polymer shell, which was named bistable EC microcapsules (BEC-Ms). However, the particle size and shell thickness of microcapsules will affect their properties, such as response time, coloration efficiency, and bistable property. In this study, BEC-Ms was prepared via solvent evaporation method filled with PMMA as the shell and the mixture of crystal violet lactone (CVL), tetrabutylammonium perchlorate (TBAP), and phase change material (PCM) as the core. The particle size and shell thickness of microcapsules were adjusted and systematically investigated by controlling the emulsification rate and mass ratio of polymer shell to core. The optimized BEC-Ms with 2 μm size and 22.94 nm thickness showed excellent performance including fast response time (about 1 s), far lower than the safety of human body drive voltage (2 V), coloration efficiency (932 cm2 C-1), and good bistability (216 h). This approach provides a viable and alternative to flexible energy-efficient wearable display-related devices and smart textiles. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Recommanded Product: 102-09-0).
Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Recommanded Product: 102-09-0
