Abstract

Nano-TiO2 can be used as ink connecting materials to improve the UV resistance due to the ability to absorb ultraviolet light of the nano-TiO2. However, the photocatalytic action of TiO2 will reduce the application performance of the ink. The nano-SiO2 coating of nano-TiO2 can block the direct contact between nano-TiO2 and the resin, which not only reduces the photocatalytic performance but also retains the ultraviolet absorption. Therefore, nano-TiO2/SiO2 composite particles were prepared using polyvinyl pyrrolidone (PVP) and 4-vinylpyridine (4VP) as dispersants. The results were shown by SEM, FT-IR, and XRD analysis. The results show that nano-SiO2 can better encapsulate nano-TiO2 when the PVP amount is 2 g, the 4VP amount is 2 ml, the titanium and silicon ratio is 1:2, and the ammonia amount is 5 ml. This study plays an active role in improving the UV resistance of inks.
