摘要：

为制备具有优异紫外线防护性能的纳米纤维,采用四氯化钛为钛源,纳米纤维素(NCC)为模板,在室温条件下诱导制备了屏蔽紫外线用金红石型纳米二氧化钛。并研究了反应温度、反应时间和四氯化钛的使用量对金红石型纳米TiO₂质量分数的影响。通过设计正交试验优化出纳米二氧化钛最佳的制备条件:反应温度为25 ℃,反应时间为1 h,四氯化钛用量为3 mL,并对其微观结构及屏蔽紫外线性能进行表征。结果表明,纯金红石型纳米TiO₂的分散性好,呈“刺球状”,粒径为100~250 nm。通过该纳米二氧化钛整理后的棉织物抗紫外线性能优异,紫外线防护系数大于40,证明此方法制备的金红石型纳米TiO₂具有良好的紫外线屏蔽性能。

Abstract:

In order to prepare nanofiber with improved ultraviolet(UV)protection performance, rutile nano-TiO₂ for UV shielding was prepared by using TiCl₄ as titanium source and nanocrystal-cellulose (NCC) as template at room temperature, and the effects of reaction temperature, reaction time and the dosage of titanium tetrachloride on the mass fraction of rutile nano-TiO₂ were studied. Orthogonal experiments were adopted to optimize the preparation conditions of nano-TiO₂, where reaction temperature was 25 ℃, reaction time was 1 h and dosage of TiCl₄ was 3 mL, and then the microstructure and UV resistance of the nano-TiO₂ were characterized. The results showed that the pure rutile nano-TiO₂ was well dispersed and has a spiny spherical shape with a particle size of 100-250 nm. The cotton fabric treated with nano-TiO₂ offers UV resistance with UPF>40, which is regarded as excellent. The rutile nano-titanium dioxide prepared by this method has good UV shielding performance, indicating that rutile nano-TiO₂ prepared by this method has good UV shielding property.

Key words: nanocrystal cellulose, TiCl₄, nano-TiO₂, rutile, UV resistance
