摘要：

The advent of 5G communication technology has led to a growing demand for materials possessing both electromagnetic interference (EMI) shielding and thermal management properties. In this study, a composite film material, multi-walled carbon nanotubes&graphene nanosheets@poly(p-phenylene benzobisoxazole)-polybenzoxazine/poly(ether-ether-ketone) (MWCNTs&GnPs@PBO-PBZ/PEEK), modified by PBZ, is presented and prepared accordingly. The hydrogen bonding and highly oriented structure results in exceptional thermal conductivity (TC). At 23.11 vol% carbon nanofiller content, it has in-plane and through-plane TC of 32.01 W & sdot; m-1 K- 1 and 3.05 W & sdot;m- 1 K- 1 , respectively. Moreover, the composite film demonstrates EMI shielding and electrical/ photothermal conversion properties, the corresponding electrical conductivity and EMI shielding effectiveness (SE) were 3830.3 S/m and 87.8 dB, respectively. Interestingly, it exhibits remarkable thermal management capabilities, characterised by efficient photothermal conversion, rapid Joule-heating response, and excellent cycling stability. It is noteworthy that the composite film is capable of not only monitoring human movement but also visualising Joule-heating performance through the introduction of thermochromic ink, thereby greatly broadening the range of potential practical applications. Overall, this work presents a novel strategy for designing PEEK-derived multifunctional composites with applications not only in artificial intelligence but also in thermal management, significantly advancing the development process of traditional polymer materials.
