Effect of Chain Length of Silane Coupling Agent for Surface Modification of Nano-TiO2
摘要
Abstract
Nano-TiO2 particles were modified respectively by silane coupling agent KH570 and KH171 with different chain length. The influence of KH570 and KH171 on the graft modifying effect of Nano-TiO2 was studied by FT-IR, TG, TEM techniques. The results show that the organic chain length of silane coupling agent can produce space steric hindrance effect. It plays a key role on modification nanometer particles. TEM show that dispersion effect on modifying nano-TiO2 by long-chain silane coupling agent (KH570) is much better. TG and wettability experiments show conent of long-chain silane coupling agent KH570 is 10% , the coupling agent grafting rate and water contact angle is maximum, respectively 8.05% and 76.6°; FT-IR show that long-chain KH570 bond strength is much stronger than KH171.关键词
