摘要/Abstract

摘要： 为了降低低温环境对人体的危害,需要开发具有高效保暖性能的材料。采用静电纺丝多射流共混技术,使用聚甲基丙烯酸甲酯(PMMA)微米纤维作为骨架支撑结构,引入聚氨酯(PU)纳米纤维提高材料的机械性能和保暖性能。通过研究环境湿度、PU质量分数、LiCl添加量以及PMMA/PU注射比对纤维絮片的影响,制备出具有联锁双网络结构的保暖材料。结果表明:PMMA/PU纤维絮片(PMMA/PUFS)具有较高的拉伸应力(159.02 kPa)和良好的拉伸伸长率(65.85%),同时具有超轻的性能(7.38 mg/cm³)和超高的保暖性(导热系数为25.28 mW/(m·K))。研究结果可为新型保暖材料的制备提供新的思路。

Abstract: It is necessary to develop materials with efficient thermal retention performance, thereby reducing the damage of low temperature environment to the human body. This study is focused on improving the mechanical properties and thermal retention of the material by using polymethyl methacrylate (PMMA)micro-fibers as the framework support structure and introducing polyurethane (PU)nano-fibers by virtue of electrospinning multi-jet blending technology. The effects of environmental humidity, PU mass fraction, LiCl addition, and PMMA/PU injection ratio on fibrous flocculus were studied, and then a thermal retention material with interlocking double network structure was prepared. The results revealed that: PMMA/PU fibrous flocculus (PMMA/PUFS)exhibited strong tensile stress of 159.02 kPa and excellent tensile elongation of 65.85%. In addition, it also exhibited good ultra-light performance (7.38 mg/cm³)and ultra-high thermal retention property (thermal conductivity of 25.28 mW/(m·K)). The research results are expected to provide a new idea for the preparation of new thermal retention materials.
