【摘要】 设计合成了一类含氟的偶氮苯，并接枝不同长度的碳链制备了三种含氟偶氮苯衍生物。通过红外光谱与核磁共振氢谱对结构进行表征。使用水性聚氨酯涂层整理的方式将三种衍生物整理到棉织物上，探究涂层织物的紫外光热响应效果，考察涂层织物的紫外防护性能以及紫外光照前后织物接触角的变化。结果表明，该涂层织物具有优异的紫外光热响应性能、紫外防护性能以及紫外调控亲疏水转变性能。涂层织物经过多个光照循环周期仍保持良好的紫外光热响应性，且具有优异的耐水性能，可用于开发多功能纺织品。更多还原

【Abstract】 A fluorine-containing azobenzene is designed and synthesized. Three derivatives are prepared by grafting the different carbon chains. Their structures are characterized using Fourier transform infrared spectroscopy(FT-IR) and proton nuclear magnetic resonance spectroscopy(1H NMR). The three derivatives are applied to cotton fabrics via water-based polyurethane coating. The photothermal response effect under the ultraviolet light of the coated fabrics is explored, and the UV protection performance of them as well as the change of the contact angle of the fabric before and after the UV irradiation are tested. The results show that the coated fabrics exhibit good UV photothermal response performance, excellent UV protection performance, and UV lightregulated hydrophobic-hydrophilic transition performance. The coated fabrics maintain good UV photothermal response after the multiple irradiation cycles and possess excellent water resistance. Thus it has application value in developing multi-functional textiles.更多还原
