Carbon based conductive polymer composites as electrothermal materials offers many merits in highflexibility, light weight, low cost, excellent processability, and rapid heating ability, however, the maximumworking temperature is usually lower than 200 C, hampering seriously the medium–high temperatureapplications. Herein, a series of rationally designed glass fiber reinforced graphite/carbonblack@polyethersulfone (G/CB@PES) composites are developed to significantly promote the maximumworking temperature over 300 C. To be specific, the introduced glass fibers acted as rigid skeleton greatlyenhance the mechanical strength of PES polymer matrix, thereby offering robust structural stability inhigh temperature working scenario. Meanwhile, glass fibers not only endow G/CB@PES composite withexcellent flame-retardant ability, but also provide rapid thermal conduction channels to reduce the riskof heat accumulation and overheating. More importantly, glass fiber reinforced G/CB@PES composites aselectrothermal film heaters exhibit superior electric heating performance in terms of fast temperatureresponsiveness, high electric heating efficiency, stable maximum working temperatures, and high electricpower efficiency under the relatively low applied voltages of 3–21 V. This work provides new insights onthe innovative design and facile fabrication of high working temperature electrothermal film heaters inemerging applications.
