摘　　要：为了使智能凝胶在纺织品功能整理中得到更好的应用,本文采用静电纺丝技术与互穿网络技术相结合,制备了一种壳聚糖季铵盐/聚-N异丙基丙烯酰胺/PEO纳米纤维,并将戊二醛作为交联剂,纳米纤维原位改性柞蚕丝织物,以赋予柞蚕丝织物温敏响应性。采用傅里叶红外光谱、TG热分析、接触角、SEM测试技术分别测定改性后柞蚕丝织物的分子结构、热性能、亲疏水性及表面形态。实验结果表明,壳聚糖季铵盐/聚-N异丙基丙烯酰胺/PEO水凝胶具有良好的温敏性,相转变温度在32~33℃,与纺丝原液水凝胶TG分析结果相符合;柞蚕丝表面形成壳聚糖季铵盐/聚-N异丙基丙烯酰胺/PEO纳米纤维层,且纤维分布均匀;改性后柞蚕丝织物具有良好的亲疏水性转变,当温度高于45℃,温敏性柞蚕丝织物具有明显的疏水性。Now,the intelligent material is taken as the development goal of the textile technology innovation key project by the national textile industry"14^(th) five-year"development plan.It will also be an important source of international competitiveness and discourse power of the textile industry.Nowadays,intelligent,highly bionic,biodegradable and other new functional fiber materials are concerned by many researchers.As one of the important development directions of modern high-tech new materials,the intelligent fiber material has been widely concerned by many researchers.Thermo-responsive textile materials can effectively transfer water with the change of external temperature.Especially on summer days with high temperature,human body will sweat a lot.In order to ensure good wearing comfort of human body,timely and rapid discharge of sweat mechanism is important.Chitosan is a natural widespread chitin by stripping acetyl role.As a kind of renewable and green material with a wealth of sources,excellent performance and good biocompatibility,chitosan is widely used in various fields including medicine,food,chemical,cosmetic,water treatment,metal extraction and recovery,biochemical and biomedical engineering,etc.But there is still a lack of high value-added applied basic research about chitosan.It is urgently to develop a high value-added application theory and technology system of natural chitosan in the field of smart fiber to realize the wide application of renewable resources with high quality.The development of new materials with high-tech,high performance and high added value functions and intelligent micro/nano fiber can provide new ideas for the development of intelligent biological new materials.In order to make the intelligent gel polymers be better applied in textile functional finish field,chitosan was first modified by quaternary ammonium salt to obtain water-soluble chitosan.Based on the above,in-situ polymerization interpenetrating polymer network technology was combined with the electrostatic spinning tech
