Application

Octavinyloctasilasesquioxane serves as a versatile organic intermediate featuring eight unsaturated double bonds. It plays a crucial role in modifying the chemical structure of copolymers and acts as a cross-linking agent in the preparation of PHBV/OVS composites through a melt-reaction technique. Additionally, it is instrumental in synthesizing highly luminescent PNC-polymer composites, which possess a superhydrophobic micro/nano structured surface. Its molecular structure allows for condensation into micro/nano-scale protrusions on PECA substrates due to strong Si-O bonding. This condensation effectively facilitates the packaging of metal halide perovskite nanocrystals, addressing the challenge of their low chemical stability against water.
