研究了交联热敏无规共聚物对棉织物舒适度的智能控制。选择摩尔比为17:3的单体甲基丙烯酸2-(2-甲氧基乙氧基)乙氧基乙酯(MEO2MA)和甲基丙烯酸乙二醇酯(EGMA)合成热敏无规共聚物聚(2-(2-甲氧基乙氧基)乙氧基乙基甲基丙烯酸酯) -co-乙二醇甲基丙烯酸酯)，缩写为P(MEO2MA-co-EGMA)。通过使用柠檬酸作为交联剂，获得的 P(MEO2MA-co-EGMA) 成功地固定在棉织物上。智能控制是通过共聚物的热响应行为实现的。当环境温度超过其转变温度时，交联的 P(MEO2MA-co-EGMA) 将崩溃。因此，以前致密的 P(MEO2MA-co-EGMA) 层将转换为多孔结构，并且增强了纺织品的透气/透湿性。由于纺织品的舒适度与透气/透湿性密切相关，因此可以实现对棉织物舒适度的智能控制。此外，含热敏聚合物和不含热敏聚合物的棉织物的柔软度没有表现出明显的变化，即使应用溶液浓度高达 16% (wt%)。相反，涂有聚（N-异丙基丙烯酰胺）（PNIPAM）的棉织物的挺度明显高于原棉织物，表明均质PNIPAM不太适合日常生活中使用的纺织品。此外，研究了白度和机械性能并在交联后保持不变。作为结果，

Smart control of cotton fabric comfort by cross-linking thermo-responsive poly(2-(2-methoxyethoxy) ethoxyethyl methacrylate-co-ethylene glycol methacrylate)

The smart control of cotton fabric comfort by cross-linking thermo-responsive random copolymer is investigated. The monomers 2-(2-methoxyethoxy) ethoxyethyl methacrylate (MEO2MA) and ethylene glycol methacrylate (EGMA) with a molar ratio of 17:3 are selected to synthesize the thermo-responsive random copolymer poly(2-(2-methoxyethoxy) ethoxyethyl methacrylate-co-ethylene glycol methacrylate), abbreviated as P(MEO2MA-co-EGMA). By using citric acid as a cross-linking agent, the obtained P(MEO2MA-co-EGMA) is successfully immobilized onto cotton fabrics. Smart control is achieved from the thermo-responsive behavior of the copolymer. Cross-linked P(MEO2MA-co-EGMA) will collapse when the ambient temperature exceeds its transition temperature. Therefore, the formerly compact P(MEO2MA-co-EGMA) layer will switch to a porous structure, and the air/moisture permeability of the textiles is enhanced. As the comfort of the textiles is closely related to the air/moisture permeability, a smart control of the cotton fabric comfort can be realized. In addition, the softness of cotton fabrics with and without thermo-responsive polymers does not show a prominent change, even when the applied solution concentration is as high as 16% (wt%). On the contrary, the stiffness of the cotton fabric coated with poly(N-isopropylacrylamide) (PNIPAM) is significantly higher than the original cotton fabric, indicating that homo PNIPAM is less suitable for textiles used in daily lives. Moreover, the whiteness and mechanical properties are studied and stay unchanged after cross-linking. As a consequence, the introduction of P(MEO2MA-co-EGMA) into textiles can provide textiles with smart control of cotton comfort, and it will not influence the wearabilities of the textiles.
