英文摘要: Ultraflexible transparent film heaters have been fabricated by embedding conductive silver (Ag) nanowires into a thin poly(vinyl alcohol) film (AgNW/PVA). A cold-pressing method was used to rationally adjust the sheet resistance of the composite films and thus the heating powers of the AgNW/PVA film heaters at certain biases. The film heaters have a favorable optical transmittance (93.1% at 26 Omega/sq) and an outstanding mechanical flexibility (no visible change in sheet resistance after 10 000 bending cycles and at a radius of curvature <= 1 mm). The film heaters have an environmental endurance, and there is no significant performance degradation after being kept at high temperature (80 degrees C) and high humidity (45 degrees C, 80% humidity) for half a year. The efficient Joule heating can increase the temperature of the film heaters (20 Omega/sq) to 74 degrees C in similar to 20 s at a bias of 5 V. The fast-heating characteristics at low voltages (a few volts) associated with its transparent and flexibility properties make the poly(dimethylsiloxane)/AgNW/PVA composite film a potential candidate in medical thermotherapy pads.
