摘要采用自制的纳米 ZnO 整理剂制备了负载纳米 ZnO 非织造布,利用 Zeta 电位及粒径分析仪研究了整理剂
的 Zeta 电位、纳米 ZnO 的粒径大小和分布;运用原子力显微镜( AFM) 研究了负载于非织造布上纳米 ZnO 颗粒分布
情况。研究结果表明:整理剂中 ZnO 颗粒的平均粒径小于 100 nm,整理后非织造布上颗粒粒径大都小于 100 nm。
负载纳米 ZnO 非织造布具有良好的光催化性能和一定的耐洗性,经洗涤 8 次后,其光催化性能依然保持在 50% 以
上;在相同的条件下,采用含有丙烯酸酯黏合剂的纳米 ZnO 整理剂处理后的非织造布耐洗牢度较好。

Abstract Nonwovens loaded with nano-ZnO was prepared with nano-ZnO finishing agent. Zeta particle
size and potential analyzer was used to examine the Zeta potential,nano-ZnO particle size and distribution
of the finishing agent. Atomic force microscopy ( AFM) was employed to study the distribution of nano-
ZnO on nonwovens. The results revealed that the average particle size of nano-ZnO finishing agent was
less than 100 nm,and most of the particle sizes on nonwovens after treatment were less than 100 nm. The
nonwoven materials loaded with nano-ZnO had good photocatalytic performance and washability. The
