摘要

Abstract

Waterborne polyurethane composites containing silica nanoparticles are synthesized successfully

via

the

in situ

polymerization. The structure

thermal stability

surface hardness

tensile strength

UV-Vis absorbance

dynamic mechanical properties and chemicals resistance of the resulting composites are investigated by FTIR

TEM

TGA

UV-Vis

DMA and chemicals soakage measurements. Results show that polyurethane molecules and silica nanoparticles are linked with covalent bonds. As a result

physical properties of polyurethane composites

such as thermal stability

surface hardness

weather and chemicals resistance are all improved when an appropriate concentration of silica nanoparticles are incorporated.
