A graphene/glass defogger is fabricated and the dynamic response of the temperature as a function of input electrical power is measured. The response time of the graphene/glass defogger is shorter by 44% than that of a Cr/glass defogger. The convective heat-transfer coefficient of graphene is 12.4 × 10−4 W cm−2 °C−1, similar to that of glass (11.1 × 10−4 W cm−2 °C−1) but smaller by 27% than that of chromium (17.1 × 10−4 W cm−2 °C−1).
