Polymer-dispersed liquid crystal (PDLC) films block UV light and have been used as smart windows, light shutters and rear screens on buildings. Generally, PDLCs are fabricated by photopolymerization using photoinitiators (PIs), which may induce film degradation by UV light. In this study, we report the fabrication of thiol-vinyl PDLC films by the polymerization-induced phase separation method without the addition of PI. The stoichiometric ratio of the thiol and vinyl monomers was optimized based on variations in the FT-IR absorbance intensity. The fabricated films displayed good electro-optical properties. The durability of the PDLC films (with and without PI) was investigated by observation under UV irradiation for 10 days, following which the films were characterised using a spectrophotometer, scanning electron microscope and polarised optical microscope. The thiol-vinyl PDLC film without PI exhibited good physicochem. durability and low haze variation under UV irradiation In the experiment, the researchers used many compounds, for example, Diethyleneglycoldiacrylate (cas: 4074-88-8Related Products of 4074-88-8).
Diethyleneglycoldiacrylate (cas: 4074-88-8) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Related Products of 4074-88-8
