Abstract

In the study, the development of cotton and wool fabrics that exhibit reversible color change and heat regulation properties was aimed. For this purpose, poly(methyl methacrylate-co-glycidyl methacrylate)/thermochromic composite 1 (PMMA/GMA/TC1) and poly(methyl methacrylate-co-glycidyl methacrylate)/thermochromic composite 2 (PMMA/GMA/TC2) microcapsules which had both of color change and heat storage properties were applied to fabrics by bath exhaustion method. Differential Scanning Calorimetry (DSC) measurement results showed that all of the fabrics could store considerable latent heat energy, as the highest melting enthalpy was obtained for Cotton 1 and Wool 1 fabrics treated with PMMA/GMA/TC1 microcapsules. The Cotton 1 and Wool 1 fabric stored the latent heat of 76.1 J/g and 89.2 J/g, respectively. According to Thermal History measurement results, microcapsule applied fabrics exhibited cooling effect resulting from the released latent heat by 1-tetradecanol which was used as the solvent component of TCs. The visual photographs and color analysis results proved that the fabrics with thermochromic property showed reversible color change with temperature variations exceeding melting.

摘要

在这项研究中，旨在开发具有可逆颜色变化和热调节特性的棉和羊毛织物。为此，聚(甲基丙烯酸甲酯-共-甲基丙烯酸缩水甘油酯)/热致变色复合材料1 (PMMA/GMA/TC1)和聚(甲基丙烯酸甲酯-共-甲基丙烯酸缩水甘油酯)/热致变色复合材料2 (PMMA/GMA/TC2)微胶囊具有通过浸浴法将变色和蓄热性能同时应用于织物。差示扫描量热法 (DSC) 测量结果表明，所有织物都可以储存大量潜热，因为用 PMMA/GMA/TC1 微胶囊处理的棉 1 和羊毛 1 织物获得了最高的熔化焓。棉 1 和羊毛 1 织物存储的潜热分别为 76.1 J/g 和 89.2 J/g。根据热历史测量结果，微胶囊应用的织物表现出冷却效果，这是由用作 TC 的溶剂组分的 1-十四烷醇释放的潜热引起的。目测照片和颜色分析结果证明，具有热致变色性能的织物随着温度变化超过熔化而呈现可逆的颜色变化。
