Abstract

Recently, the application of nano-SiO2 in composite materials has received wide attention. In this work, a new method was explored to prepare nano-SiO2 using phenol instead of other organic alcohols. The obtained nano-SiO2 was characterized by Fourier transform infrared spectroscopy (FT-IR) and by the zeta potential method. The phenol dispersant containing the prepared nano-SiO2 exhibited much higher reactivity toward formaldehyde than pure phenol. The preparation parameters of phenolic resin (PR) involved by nano-SiO2 were mild. This novel phenolic resin was successfully applied to fabricate a phenolic foam (PF) with a 153% increase in compressive strength.
