Multifunctional AgNW@MXene decorated polymeric textile for highly-efficient electro-/photothermal conversion and triboelectric nanogenerator

In this work, we demonstrate multifunctional and flexible polymeric wearable heaters with highly-efficient electro-/photothermal performance by constructing 3D [email protected] conductive network on the fiber surface, which is realized by a simple alternating solution dip coating technique. The temperature of [email protected] decorated polymeric textile (AM-textile) heater can reach to a high value of 215 ℃ at comparable low voltage (3.5 V), and to 224 °C rapidly within 10 s under a near infrared laser light (100 mW). In addition, a triboelectric nanogenerator using the AM-textile as electrode can transform electrical signal with an open circuit voltage of 62 V through collecting energy from small human movement. Meanwhile, the AM-textile not only maintains the breathability and flexibility of the pristine polymeric textile, but also exhibits excellent antibacterial, flame retardant, and electromagnetic interference shielding ability at the same time, showing great potential for applications in multifunctional wearable heater and self-powered electronic device.
