Abstract

The nano-SiO₂ is used to modify the waterborne polyurethane, and the morphology and performance of the waterborne polyurethane (are studied in) prepared by the in-suit polymerization method and the blending method. The properties and structure have been characterized by fourier transform infrared spectra (IR), differential scanning calorimetry (DSC), Thermal gravimetric (TG), transmittance electron microscopy (TEM) and Dynamical Mechanical Analysis(DMA). The experiment results show that, compared with the blending method, the in-suit polymerization has more advantages in that the nano-SiO₂ is evenly dispersed in the waterborne polyurethane, obviously in microphase separation and better in resistance to high temperature and water.
