Overview | trimethylmethoxysilane can be used as a precursor to change the degree of internal crosslinking of the aerogel, thus making the aerogel flexible; the flexible SiO2 aerogel was prepared by adjusting the ratio of trimethylmethoxysilane to solvent, and then the appropriate phase change core material was selected. |
Use | trimethylmethoxysilane is a silane coupling agent with great use as a capping agent for silicone oils and linear polysiloxanes. |
