摘　　要：为解决目前衬垫材料弹性较差及缺乏功能性的问题,采用化学溶液法合成了纳米ZnO材料,将其分散到聚氨酯(PU)发泡胶液中与非织造聚酯纤维绵基材进行复合,制备出一种功能性发泡复合绵材料。对纳米ZnO的形貌与结构进行表征,测试了复合绵的压陷回弹性能、光催化特性、防紫外线性能及落球回弹性能。结果表明:合成的纳米ZnO是由直径为30 nm、长为5μm的纳米棒组成的纳米花,单个纳米棒为六方相;复合绵具有不规则的孔洞结构,其落球回弹率最高可达到58.9%;聚氨酯含量越高,复合绵的压陷回弹性越好;添加纳米ZnO后,复合绵在900 min内可将甲基橙完全降解,其紫外线防护系数值随ZnO质量分数的增加而升高,且稳定性好。In order to improve elasticity and enhance functions of nonwoven fabric,the research introduced in this paper used a chemical solution method to synthesize nano-ZnO,dispersed it into a polyurethane(PU)foam gel and then compounded with nonwoven polyester fabric substrate to prepare a new functional elastic material.Morphology and structure of the obtained nano-ZnO,and the indentation resilience,photocatalytic performance,ultraviolet protection and ball rebound resilience of the composite sponge were analyzed.The results show that the synthesized nano-ZnO is a nano-sized flower composed of nanorods with a diameter of 30 nm and a length of 5μm.The composite sponge has a non-standard hole structure,and its ball rebound rate reaches 58.9%.It is show that the higher the PU content,the better the ball rebound resilience.After adding nano-ZnO,the composite sponge can completely degrade the methyl orange within 900 min.The ultraviolet protection factor value becomes higher with enhanced stability with the increase of ZnO content.
