Three-dimensionally conformal porous microstructured fabrics (3CPMFs) are a new kind of modified fabrics with three-dimensionally conformal porous microstructures of introduced materials recently developed for wearable technology. They can effectively introduce customized functional performance based on the choice of brick materials, while at the same time maintain the excellent inherent properties of textiles. In this paper, based on the introduction of polystyrene with low thermal conductivity at only 8 × 10 g cm, we developed a kind of polyester fabric-based 3CPMF with enhanced thermal insulation, while maintaining its unique fabric texture, flexibility, moisture permeability, and light weight. It was demonstrated to be a good textile material for the fabrication of wearable electrothermal textile (ET) devices with enhanced thermal management. Compared to pristine fabric-based ET devices, this kind of 3CPMF-based ET devices can obtain higher temperatures under the same input power to provide thermal comfort for human beings, while saving more electric power to achieve the same thermal equilibrium temperature. We believe that, based on the choice of different functional materials and textiles, a wide range of 3CPMFs with customized functionalities and properties can be designed and developed for the realization of a brand-new class of truly wearable devices with desired functional performance and daily garment-like safety and comfort.
三维共形多孔微结构织物（3CPMFs）是一种新型的改性织物，具有三维共形多孔微结构，是最近为可穿戴技术开发的引入材料。它们可以根据砖材料的选择有效地引入定制的功能性能，同时保持纺织品优异的固有特性。本文基于仅引入导热率低至8×10 g cm的聚苯乙烯，开发了一种具有增强隔热性能的聚酯基3CPMF，同时保持其独特的织物质地、柔韧性、透湿性和轻质特性。结果表明，它是一种用于制造具有增强热管理功能的可穿戴电热织物（ET）器件的良好纺织材料。与基于原始织物的ET器件相比，这种基于3CPMF的ET器件在相同输入功率下可以获得更高的温度，为人类提供热舒适性，同时节省更多电力以达到相同的热平衡温度。我们相信，基于不同功能材料和纺织品的选择，可以设计和开发出具有定制功能和特性的多种3CPMF，以实现一类全新的具有所需功能性能以及日常服装般安全性和舒适性的真正可穿戴设备。
