Descripción

Application

Hexadecyltrimethoxysilane (HDTMS) may be used to prepare hydrophobic silica aerogels by sol-gel process.{80} HDTMS was coated upon silica covered aluminum pigments.{81} Metal nanoparticles (CeO₂, Fe₂O₄, TiO₂, ZnO) coated with HDTMS form stable dispersions in hydrocarbon solvents. {82} HDTMS may be used to functionalize polyisocyanurate (PIR) foams {84} and graphene.{83}
