Descrizione generale
Diethoxydimethylsilane (DEDMS) is an organically modified silicate (ORMOSIL) with two methyl groups in each unit that facilitate the hydrophobic characteristics. It is mainly utilized to functionalize a variety of substrates.
Applicazioni
Diethoxydimethylsilane (DMDES) may be used to modify epoxy resin6 and the surfaces of pure silica and Pd/SiO2 hydrogen gas sensors. Surface modification results in enhanced gas sensing properties of the sensors. {43}-{44}Diethoxydimethylsilane may be used as a precursor for the synthesis of ultrafine SiC powder. {45} Studies report its use as a precursor for ORMOSIL (Organically modified SILicates) and thin a-SiOxCyHz films.{47}
The composite of DEDMS and triethoxymethylsilane can be used to synthesize a liquid precursor resin for the preparation of silicon oxycarbide (SiOC). It can form a sol-gel coating on polyamide-polyethylene (PA/PE), which can be used as an anti-oxidizing food packaging material. It can also be used as a precursor in the synthesis of polydimethylsiloxane, which forms an anti-corrosive coating composite with waterborne polyurethane.
