Animals living in the extremely cold environment, such as polar bears, have shown amazing capability to keep warm, benefiting from their hollow hairs. Mimicking such a strategy in synthetic fibers would stimulate smart textiles for efficient personal thermal management, which plays an important role in preventing heat loss and improving efficiency in house warming energy consumption. Here, a “freeze‐spinning” technique is used to realize continuous and large‐scale fabrication of fibers with aligned porous structure, mimicking polar bear hairs, which is difficult to achieve by other methods. A textile woven with such biomimetic fibers shows an excellent thermal insulation property as well as good breathability and wearability. In addition to passively insulating heat loss, the textile can also function as a wearable heater, when doped with electroheating materials such as carbon nanotubes, to induce fast thermal response and uniform electroheating while maintaining its soft and porous nature for comfortable wearing.

北极熊头发启发的隔热纺织品

得益于空心毛，生活在极冷环境中的动物（例如北极熊）显示出惊人的保暖能力。在合成纤维中模仿这种策略将刺激智能纺织品进行有效的个人热量管理，这在防止热量散失和提高房屋取暖能耗方面发挥着重要作用。在这里，使用“冷冻纺丝”技术来实现连续且大规模的制造具有对齐的多孔结构的纤维，模仿北极熊的毛发，而这是其他方法难以实现的。用这种仿生纤维编织的纺织品显示出优异的绝热性能以及良好的透气性和耐磨性。除了被动隔离热量损失外，纺织品还可以用作可穿戴加热器，
