▎ 摘　　要

In this work, a graphene-based film heater is proposed based on laser-reduced graphene oxide (LRGO) fabricated by the simple and eco-friendly laser direct writing technology at ambient conditions. Benefiting from high photothermal effect of CO2 laser with wavelength of 10.6 um, the LRGO-based film heater has a high heating rate of 15.3 degrees C/s up to 196 degrees C with a fast response of 12.84 s at a low power density of 1 W/cm(2). Moreover, it exhibits good anti-interference ability to the mechanical effect and shows potential important application for de-icing. This work is helpful for the development of graphene-based device in practical application. (c) 2020 Published by Elsevier B.V.
