Silicone based nanocomposites including inorganic nanoparticles and their methods of manufacture and use

摘要

Silicone-based nanocomposites that include a plurality of multimodal nanoparticles dispersed within a silicone-based polymeric matrix are provided. Each of the multimodal nanoparticle has a first plurality of long silicone compatible polymeric chains and a second plurality of short silicone compatible polymeric chains grafted onto a surface of a nanoparticle (e.g., an inorganic nanoparticle, such as silica, alumina, titania, indium tin oxide, CdSe, etc.), with the short silicone compatible polymeric chains present on each multimodal nanoparticle at a higher grafting density than the long silicone compatible polymeric chains. Methods are also provided for forming a silicone-based nanocomposite.
