摘要
本文主要用液相沉积法对纳米二氧化钛进行了表面包覆改性,用FTIR对其进行表征,运用牛津杯法研究其抗菌性能,并对其抗菌机理进行了探讨。结果表明通过包覆SiO2可在TiO2表面形成致密的硅氧化物膜,防止团聚的发生,有效的改善了其在水溶液中的分散稳定性;抑菌实验表明在相同条件下,SiO2-TiO2显出了优异的抗菌性能并随着浓度的增加其抑菌性能增强。
Nano-TiO2 was modified on its surface by chemical liquid deposition with SiO2 and the dispersion properties were study.The inhibition of its antibacterial activity on microorganisms was studied by the method of Oxford-cup tests and the antibacterial mechanism was discussed.The result show that attached silicon dioxide can reduce the product size and improve stability and stability of nano-TiO2 in water.The composite material doped with SiO2 has outstanding antibacterial activities and has less influence on antibacterial activity.
