Effect of Various Amide Additives on the Tetramethoxysilane sol-gel Process

摘要

The effects of various amides, including formamide, N-methylformamide, N, N-dimethy)formamide, acetamide, N-methylacetamide and N, N-dimethylacetamide, on the pore mophology of resulting xerogels prepared from tetramethoxysilane are studied by the BET pore analysis method. Shear viscosity and NMR line width measurements provide additional information about the effects of additives on the sol-gel process.
