What is Octavinyloctasilasesquioxane?

Description

Octavinyloctasilasesquioxane (OVS) is a useful organic intermediate with eight unsaturated double bonds, and it can be used to adjust the chemical structure of copolymer. It could used as a cross-linking agent to prepared the PHBV/OVS ;composites by melt-reaction technique. It is also used to synthesize highly luminescent PNC-polymer composites with a superhydrophobic micro/nano structured surface. The OVS is condensed into the micro/nano-scale protrusions (second phase) on the PECA substrate because of the strong Si-O bonds between OVS molecules to [1-2]. This method can achieve the purpose of packaging Metal halide perovskite nanocrystals and solve the problem of the low chemical stability against water.
