To improve mechanical and electrical properties of UV-cured coatings or films, antimony doped tin oxide (ATO) nanoparticles have been used. In this study, ATO nanoparticles were grafted by 3-glycidyloxypropyltrimethoxysilane (GPTS) and 3-methacryloxypropyltrimethoxysilane (MPS) respectively to improve dispersion and interfacial adhesion in a UV-curable polyester-acrylate resin system. The organic modification of ATO nanoparticles were confirmed by FTIR spectroscopy and thermogravimetric analysis (TGA). The physical properties of the nanocomposite films were examined by universal testing machine, pencil hardness tester, TGA and UV-visible spectroscopy. UV-curing behavior of the nanocomposite system was investigated by FTIR spectroscopy. The physical properties of the nanocomposite films were considerably improved by introducing the modified ATO nanoparticles. |
