Abstract
AbstractIn this study, hydrofluorosilicone oil with a cyclic structure () and tetramethyl‐tetravinylcyclotetrasiloxane () are synthesized through a hydrosilylation reaction with platinum as the catalyst to obtain high ultraviolet transmittance fluorosilicone. The curing process of fluorosilicone resin is monitored by Fourier transform infrared spectroscopy. The effects of differentAvalues (the molar ratio of Si─H to vinyl) on the curing process, mechanical properties, glass transition temperature, crosslinking density, hydrophobicity, and UV transmittance are studied. The results demonstrate that with the increase in theAvalue, the initial curing temperature and the temperature at the completion of curing decrease, the tensile strength initially increases and then decreases, and the glass transition temperature and crosslinking density increase. Furthermore, the contact‐angle and UV transmittance initially increase and subsequently decrease, the maximum contact‐angle is 107.61°, which shows good hydrophobicity, and the maximum UV transmittance at 351 nm reaches 93.66%.
