Abstract
Hydroxyl-terminated polydiphenyl-methylphenyl siloxane (PDPMPS-OH) was synthesized by a non-hydrolysis sol–gel condensation method, using diphenylsilanediol (DPDS) and methylphenyl dimethoxysilane (MPDMS) as the raw materials. Subsequently, the synthesized PDPMPS-OH was reacted with divinyltetramethyldisiloxane (MMvi) to produce a vinyl-terminated polydiphenyl-methylphenyl siloxane (PDPMPS-Vi) with a high refractive index of 1.580 and a long chain linear structure. The optical adhesive product (CSOA) cured by PDPMPS-Vi and a hydrogen-containing silicone resin, exhibits excellent optical performance, high reliability, and significantly enhanced tensile strength (up to 384 kPa), hardness (up to 48 O), and elongation at break (up to 237.9%), as well as a refractive index of up to 1.575. This adhesive demonstrates remarkable performance as an optical component adhesive.
期刊介绍：
The journal Silicon is intended to serve all those involved in studying the role of silicon as an enabling element in materials science. There are no restrictions on disciplinary boundaries provided the focus is on silicon-based materials or adds significantly to the understanding of such materials. Accordingly, such contributions are welcome in the areas of inorganic and organic chemistry, physics, biology, engineering, nanoscience, environmental science, electronics and optoelectronics, and modeling and theory. Relevant silicon-based materials include, but are not limited to, semiconductors, polymers, composites, ceramics, glasses, coatings, resins, composites, small molecules, and thin films.
