摘要
多丙烯酸酯基化合物和多氨基化合物在饱和电解质溶液与醇类液相组成的混合体系中发生室温凝胶反应,通过长链烷基胺修饰制得超支化聚合物(HBPs)。以荧烷染料ODB-1、双酚A、十四醇为原料,采用混合方式制备温致变色复合物(TCC)。将超支化聚合物与温致变色复合物进行物理共混,构筑智能响应性变色颗粒产物,基于热黏合法构制温致颜色与润湿性可切换智能织物涂层,并展开可视化传感应用。结果表明:HBPs基颗粒涂层具有抗污自清洁性能和化学稳定性。TCC最低相变温度为35.9℃、变色时间为82 s、复色时间为39 s、变色前后色差为9.73,达到较好的变色效果。HBPs-TCC基织物涂层温致变色和亲疏水转换特性显著,可在不同温度的金属、玻璃和皮肤表面实施可视化传感应用,且能够循环使用。
Hyperbranched polymers(HBPs)are produced by modification with long chain alkyl amines through room temperature gelation reaction of polyacrylate-based compounds and polyamino compounds in a mixed system consisting of saturated electrolyte solution and alcohol liquid phase.The thermochromic complexes(TCC)are prepared by mixing fluorescent alkane dye ODB-1,bisphenol A and tetradecanol as raw materials.Physical blending of hyperbranched polymers with thermochromic complexes leads to the construction of smart-responsive color-changing particle products.Thermotropic color and wettability switchable smart fabric coating is prepared based on thermobonding method,and its visual sensing application is investigated.The re⁃sults indicate that HBPs based particle coatings have anti fouling and self-cleaning properties as well as chemi⁃cal stability.The lowest phase transition temperature of TCC is 35.9℃,the color change time is 82 s,the recol⁃or time is 39 s,and the color difference before and after color change is 9.73,achieving a good color change ef⁃fect.The HBPs-TCC based fabric coating exhibits significant thermochromic and hydrophilic hydrophobic con⁃version properties,and can be used for visual sensing applications on metal,glass,and skin surfaces at differ⁃ent temperatures.Also,it can also be recycled.
