Abstract

Personal thermal management (PTM) technology, which predominantly utilizes phase change materials (PCMs) has emerged as an effective strategy for mitigating thermal stress. However, how to impart intrinsic flexibility and vibrant colors to meet practical application needs remains a topic that requires further research and effort. In this thesis, a novel intrinsically flexible PCM with notable shape stability, vivid and eye-catching colors for PTM was synthesized. The flexible PCMs demonstrate a high phase change enthalpy (102.1 J/g), while maintaining thermal stability over 100 cycles. In addition, they can chemically bond with dye molecules, displaying vivid colors with extremely low dye usage (0.05 wt%). The integration of PCMs with fabrics using a hot press method produces a fabric that closely conforms to the human body and exhibits strong colorfastness, demonstrating significant potential for thermal management in specialized garments.

具有内在灵活性的多彩相变材料，用于个人热管理

个人热管理（PTM）技术主要利用相变材料（pcm），已成为缓解热应力的有效策略。然而，如何赋予其内在的灵活性和充满活力的色彩以满足实际应用的需要仍然是一个需要进一步研究和努力的课题。本文合成了一种具有良好形状稳定性、色彩鲜艳、吸人眼眼球的新型固有柔性PCM。柔性pcm表现出高相变焓（102.1 J/g），同时在100次循环中保持热稳定性。此外，它们可以与染料分子化学键合，以极低的染料用量（0.05% wt%）显示鲜艳的颜色。使用热压方法将pcm与织物相结合，生产出与人体紧密贴合的织物，并具有很强的色牢度，显示出在专门服装的热管理方面的巨大潜力。
