Durable abrasion resistance is the critical capability for the functional textile via coating treatment routes. Here, an abrasion resistant fabric-based Joule heater with sandwich structure was fabricated via spraying in sequence of water-soluble polyurethane (WPU), then composite ink of graphene, WPU and tourmaline, and at last WPU. The composite fabrics with the incorporation of tourmaline exhibited favorable electrothermal performance, which could achieve a steady-state temperature of 75.4 °C in 30 s under 10 V voltage, and possessed a high power density (2 × 103 W/m2). The flexible heater exhibited remarkable abrasion shielding performance, only resulting in 21.1% electrical conductivity reduction after a 2500-cycles abrasion test, far less than the 87.0% of fabrics without a sandwich structure. The application on thermal therapy of the hand exhibited 1.8 °C rise of blood vessel around the heater under 8 V voltage. Therefore, the as-obtained Joule heater can be widely applied in functional protective garments and medical electro-heating wearable devices.

通过喷涂工艺具有持久耐磨性的高效电热石墨烯/电气石复合织物焦耳加热器
耐用的耐磨性是功能性纺织品通过涂层处理路线的关键能力。在此，通过依次喷涂水溶性聚氨酯（WPU），石墨烯，WPU和电气石的复合油墨，最后喷涂WPU，制造出具有三明治结构的基于耐磨织物的焦耳加热器。掺入电气石的复合织物具有良好的电热性能，在10 V电压下30 s内可达到75.4°C的稳态温度，并具有高功率密度（2×10 3 W / m 2））。柔性加热器表现出卓越的耐磨性能，在2500次循环的磨损测试后，仅导致21.1％的电导率降低，远低于没有夹层结构的织物的87.0％。在手部热疗上的应用显示，在8 V电压下，加热器周围的血管上升了1.8°C。因此，所获得的焦耳加热器可以广泛地用于功能性防护服和医疗电加热可穿戴设备中。
