Sol-gel processing of organic/inorganic composite materials has attracted much study in recent years. The low temperature sol-gel process and its inherent versatility allow microstructural control on the nanoscale, leading to many interesting materials. In this preliminary study, we have synthesized silica/poly(vinyl acetate) (SiO2/PVAc) composite materials and investigated the effect of formamide substitutions for ethanol as the solvent. The interaction between SiO2 and PVAc is primarily hydrogen bonding between silanols on the silica surface and the carbonyl groups of the PVAc. The time to gel, skeletal density, and the linear shrinkage were significantly dependent on the presence and quantity of formamide. Nitrogen sorption was used to evaluate the xerogels structures. The thermal behavior was studied with thermogravimetry/Fourier transform infrared spectroscopy (TG/FTIR).
