摘要:
将制备锐钛矿TiO2纳米无机粒子工艺与纤维化学改性工艺相结合,以钛酸四丁酯为原料,由纳米粒子表面的羟基与纤维的活性羧基发生酯化反应而接枝在纤维表面,制备出光催化抗菌纤维。本文研究了钛酸四丁酯酯溶液浓度、pH值、温度和时间对接枝率的影响,结果表明,接枝率越高,抗菌性越强,反应物浓度为0.1 mol/L、pH值为4、温度为75 ℃、时间为2 h时,接枝率达到16.40%。
Abstract:
Photocatalysis antibacterial fiber was prepared by using titanium butyrate as a precursor integrating techniques of anatase nano-TiO2 preparation and chemical modification,in which grafted of fiber surface was formed by esterification of the hydroxyl groups on nano-TiO2 with the carboxyl groups on the fiber. Effects of concentration,pH value,temperature and time on the graft ratio were studied. Results showed that the antibacterial ability of fiber is enhanced with the increase in graft ratios. A graft ratio of 16.40% was achieved with 0.1 mol/L of concentration at pH 4 under 75 ℃ for 2 h.
