摘　　要：Multifunctional,wearable,and durable textiles integrated with smart electronics have attracted tremendous attention.However,it remains a great challenge to balance new functionalities with high-temperature stability.Herein,textile-based pressure sensors with excellent electromagnetic interference(EMI)shielding,Joule heating,and high-temperature resistance were fabricated by constructing graphene/SiC(G/SiC)heterostructures on carbon cloth via laser chemical vapor deposition(LCVD).The resultant textiles exhibited excellent EMI efficiency of 74.2 dB with a thickness of 0.45 mm,Joule heating performance within a low working voltage(V)range of 1-3 V,and fast response time within 20 s.These properties arose from multiple reflections,interfacial polarization,and high conductivity due to the numerous amounts of nanoscale G/SiC heterostructures.More importantly,G/SiC/carbon fibers(CFs)demonstrated well high-temperature resistance with a heat resistance index(THri)of 380.2 C owing to the protection of a coating layer on the CFs upon oxidation.Meanwhile,the G/SiC/CFs presented good pressure-sensing performance with high sensitivity(S)of 52.93 kPal,fast response time of 85 ms,and a wide pressure range of up to 186 kPa.These features imply the potential of the G/SiC/CFs as efficient EMI shielding,electrical heater,and piezoresistive sensor textiles.
