Adaptive and Remote Thermoregulation Enabled with a Highly Stable Transparent Flexible Heating Film

Precise and remote control in thermoregulation is essential in intelligent life. Heating films with appropriate electrical, optical, and mechanical properties are key components of thermal control systems for versatile applications. Here, we demonstrate an adaptive thermoregulation remote collaborative platform using a highly transparent and stable flexible passivated silver nanowire (AgNW) electrothermal film. The perfluorinated polymeric sulfonic acid passivation of the AgNW network can inactivate the film to possess superior stability of continuous heating operation (42 degrees C, 48 h) and high optical transmittance in the visible region (>85%, 4 months) under ambient conditions, as well as a weld nanowire junction for efficient and tunable thermal emission with low operating voltage (20-100 degrees C, <6 V). By further integrating the heater with a remote negative feedback adaptive control circuit, this system can realize wireless rapid precision temperature control (<1 degrees C), effective energy utilization with a power saving of similar to 34%, and adaptive regulatory stability against external interference. Utilizing the intelligent heater as a tint film has reliable capability of antifog and snow/ice removal, showing great potential in smart homes, automotive electronics, and smart agriculture.
