供暖消耗大量能源，是温室气体排放的主要来源。尽管在改善隔热和设计的基础上，节能建筑正在迅速发展，但很大一部分能源仍被浪费在对空旷空间和非人类物体的加热上。在这里，我们演示了一种使用金属纳米线嵌入布料的个人热管理系统，可以减少这种浪费。金属纳米线形成了一个导电网络，不仅因为它反射了人体的红外辐射而具有高度的隔热性能，而且还允许焦耳加热来补充被动绝缘。不会因为纳米线的多孔结构而牺牲原始布料的透气性和耐用性。与传统的室内加热器相比，这种纳米线布可以有效地为人体取暖，每人节省数百瓦的电量。
Heating consumes large amount of energy and is a primary source of greenhouse gas emission. Although energy-efficient buildings are developing quickly based on improving insulation and design, a large portion of energy continues to be wasted on heating empty space and nonhuman objects. Here, we demonstrate a system of personal thermal management using metallic nanowire-embedded cloth that can reduce this waste. The metallic nanowires form a conductive network that not only is highly thermal insulating because it reflects human body infrared radiation but also allows Joule heating to complement the passive insulation. The breathability and durability of the original cloth is not sacrificed because of the nanowires porous structure. This nanowire cloth can efficiently warm human bodies and save hundreds of watts per person as compared to traditional indoor heaters.
