The flexible pressure-sensitive adhesive graphene-based composite heater based on the laminating structure for de-icing applications

The laminating flexible pressure-sensitive adhesive graphene-based composite heater (FPGH) coupled with advantages of excellent Joule heating performance, thermal stability, conductive anisotropy, and mechanical properties is prepared by the tape casting method. Meanwhile, the heater shows eco-friendly and light-weight features, which can be applied as the shape-costuming flexible de-icing heater on various substrates. The heating temperature reaches 142.9 °C at a bias voltage of 6 V with low power of around 2.1 W. Moreover, the T5min (the surface temperature of the FPGH after applying a voltage for five minutes) remains stable after 4000 folds. Additionally, the heater can be directly adhered to different substrate surfaces by applying pressure due to the excellent pressure-sensitive adhesive property of the styrene-butadiene rubber (SBR) layer. Besides, the conductive anisotropy also prevents electric leakage. The de-icing rate (12 V) of FPGH is 28 times higher than that of the pure SBR, and its electrical conductivity remains almost invariant even at cryogenic temperature environments. The results confirm that the FPGH is a promising and competitive heater for de-icing applications.
