The adsorption of 3-glycidoxypropyltrimethoxysilane (GPS) onto silica colloids (20 nm diameter) suspended in an isopropanol/water solution was studied and related to the microstructure and properties of coatings prepared from the suspensions. 29Si NMR results indicate an adsorption limit of approximately 2.2 GPS monomer or repeat units per nm2 of silica surface after 24 h in suspension. For coatings dried at 100 degreesC, FTIR data show that surface silanols are further consumed as GPS is added… CONTINUE READING
