半互穿纤维絮片表征测试数据集

生活在寒冷气候下的人们迫切需要保暖设备来保持健康。然而，创造既能有效保暖又能保持稳定结构的坚固机械性能的材料极具挑战性。在本文中，我们报道了一种通过直接静电纺丝和热交联制备超轻、机械强度高和高性能保暖材料的简单而省时的策略。具有立体纤维网络的蓬松纤维组件通过湿度诱导静电纺丝技术制造，随后加热以在纤维内产生半互穿聚合物网络(semi-IPNs)以获得纤维海绵(FSs)。半互穿纤维絮片具有高拉伸应力、良好的抗疲劳性(1000次循环拉伸或压缩试验后塑性变形为0%)和在液氮(196℃)中无损回弹的综合性能。此外，半互穿纤维絮片表现出2.2mg/cm3的低体积密度、有效的保温能力以及理想的防水性和透气性。半互穿纤维絮片的成功合成为开发具有强大机械性能的高性能保暖材料提供了一种新的尝试。

People living in cold climates urgently require thermal insulation equipment to maintain their health. However, developing materials that can deliver effective thermal insulation while possessing stable structures and robust mechanical properties poses significant challenges. In this paper, we report a simple and time-saving strategy for preparing ultralight, high-mechanical-strength and high-performance thermal insulation materials via direct electrospinning and thermal crosslinking. Fluffy fiber assemblies with three-dimensional fiber networks are fabricated via humidity-induced electrospinning, followed by heating to generate semi-interpenetrating polymer networks (semi-IPNs) within the fibers, yielding fiber sponges (FSs). The semi-IPN fiber sponges exhibit comprehensive properties including high tensile stress, excellent fatigue resistance (0% plastic deformation after 1000 cycles of tensile or compression tests) and damage-free rebound in liquid nitrogen (-196 ℃). Furthermore, the semi-IPN fiber sponges show a low bulk density of 2.2 mg/cm³, effective thermal insulation performance, as well as desirable water resistance and air permeability. The successful fabrication of semi-IPN fiber sponges provides a novel approach for developing high-performance thermal insulation materials with robust mechanical properties.
