Phenol-formaldehyde resin is used as the most adhesive to produce waterproof plant-based composite. However, this product contains phenol and formaldehyde which can be easily released to pollute air. Based on the single-factor method, the effect of nano TiO2 on situation of cure and pyrolytic reaction of PF resin was studied by FT-IR and Py-GC/MS. The result of FT-IR spectrograms showed that the absorbencies of Ar-OH, Ar and Ar-O-Ar of PF/TiO2 composite were lower than that of PF, and there were no peaks of PF/ TiO2 composite at 820cm(-1) and 760cm(-1), indicating that nano TiO2 couldn't impro...
