N2 - To enhance the interfacial interaction in silica nanoparticles filled polymer composites, nano-SiO2 gel was prepared by a sol-gel route, and then it was modified in situ through a reaction of silane coupling agent with hydroxyl on the surface of SiO2. The modified nano-SiO2 gel was added to the system of light-cured varnish to prepare UV light-cured nanocomposite varnish. The structures and properties of varnish were studied using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and film performance test. The results showed that the modified nano-SiO2 was well dispersed in the varnish. After introduction of modified nano-SiO2, the fracture morphology of varnish film showed a corrugated shape, indicating the ductile fracture. The wear resistance of the varnish film increased by 50%, the coefficient of static friction reduced about 15%, and gloss improved to some extent.
