Abstract

A new method of surface chemical modification of nano-SiO₂ is proposed in this paper. In the presence of catalyst, the active hydroxyl groups on the surface of nano-SiO₂ reacted with AB₂-type monomer (N, N-dihydroxyethyl-3-amino methyl propionate) by one-step polycondensation. And the product's Fourier transform infrared (FTIR) graphs and transmission electron microscopy (TEM) images proved that hyperbranched poly (amine-ester) was grafted on nano-SiO₂ surface successfully. Results show that the modified nano-SiO₂ exhibits excellent dispersion and stability in some solvents such as alcohol and chloroform.
