Methoxytrimethylsilane is used as a end-capping agent for poly(siloxane). Its hydrophobicity can also enhance the anti-cracking performance of composite materials. It can be used as a precursor to change the cross-linking degree inside aerogels, so that the aerogels become flexible. By adjusting the ratio of Methoxytrimethylsilane to solvent, flexible SiO2 aerogels can be prepared, and then suitable phase change core materials are selected. SiO2 aerogel phase change composites are obtained by vacuum impregnation, which have the advantages of good mechanical properties, strong structural adjustability and high loading rate. This product can also be used as a silanizing reagent for protecting hydroxyl, amino, carboxyl groups, etc., without releasing ammonia and hydrogen chloride. It has high value in the synthesis of pharmaceutical intermediates. |
