Application
Dimethoxydimethylsilane serves as a versatile compound with several applications. It is primarily employed in synthesizing macroporous silica aerogels, which have unique properties for various scientific and industrial uses. Additionally, it is utilized in the preparation of hollow silica nanoparticles that are loaded with phthalocyanine, facilitating near-infrared photodynamic and photothermal combination therapies, which hold promise in medical treatments. It is also an essential component in creating dielectric silicone elastomers with high dielectric permittivity, valuable in electrical and electronic applications. As a monomeric alkylalkoxysilane, it hydrolyzes upon contact with water, releasing methanol and forming reactive silanols, which condense into oligomeric and polymeric siloxanes. Beyond these applications, Dimethoxydimethylsilane is instrumental in the synthesis of chemical intermediates, enhances the production of silicone resins, and is used in the hydrophobization of surfaces such as glass and pigments, making them more resistant to water.
