Abstract

This article aims to study the thermo-regulating properties of infiltrated Phase change material (PCM) micro-particles treated on polyester fabric. The melt infiltration method was implemented for the synthesis of the Silica aero-gel/Eicosane particles by dispersing eicosane in silica aero-gel. Synthesized particles were incorporated into the polyester knitted fabric by both exhaustion dyeing and coating method to impart the thermoregulation characteristics. The crystalline structure and the particle size of aero-gel infiltrated PCM particles were measured by X-ray diffraction (XRD) analyzer. The presence of eicosane particles deposited on the fabric surface was confirmed by the Fourier Transform Infrared Spectroscopy (FT-IR) and Scanning Electron Microscope (SEM). Finally, while the sample was subjected to heating, both the dyed and coated fabric showed resistance against the rise of temperature due to the presence of phase transition PCM micro-particles compared to the untreated raw fabric sample.

摘要

本文旨在研究经处理的相变材料（PCM）微粒渗透到聚酯织物上后的热调节性能。通过将二十烷分散在二氧化硅气凝胶中，采用熔体渗透法合成了二氧化硅气凝胶/二十烷微粒。通过浸染和涂层法将合成的微粒掺入聚酯针织物中，以赋予其热调节特性。采用X射线衍射（XRD）分析仪测量气凝胶渗透PCM微粒的晶体结构和粒径。通过傅里叶变换红外光谱（FT-IR）和扫描电子显微镜（SEM）确认了沉积在织物表面的二十烷微粒的存在。最后，在对样品进行加热时，与未处理的原始织物样品相比，由于存在相变PCM微粒，染色和涂层织物均表现出对温度升高的抗性。
