Anti-UV Nanoparticles Surface Modification Technology
Abstract:
The grafting mechanism of KH570 in the nanometer ZnO/CeO2 composite powders is discussed. The influences of the reaction time, amount of coupling agent on the grafting rate are researched based on graft situation characterized with FT-IR and XRD devices. The research shows that the ZnO/CeO2 can be distributed evenly after be grafted with KH570. As a result, the performance of anti-UV and the lipophilic degree of modified nanometer ZnO/CeO2 will enhance. The modified nanometer ZnO/CeO2 will be distributed evenly in spinning solution while the spinning melted with NYLON 6 in high-temperature furnace. When the reaction time is 2 hours, the mass ratio of coupling agents and nanoparticle is 0.3, the grafting ratio can reach the maximum.
