Abstract The continuous advancement and miniaturization of modern electronics have increased challenges related to electromagnetic interference (EMI) thermal management. Polymer materials are commonly used for regulation EMI shielding because their low weight, cost‐effectiveness, ease processing. However, achieving both high effectiveness (SE) superior conductivity (TC) in polymeric systems remains a major scientific challenge. In this study, lightweight flexible amino‐functionalized multiwalled carbon nanotube‐graphene nanoplatelet/poly(p‐phenylene benzodioxazole)/poly(ether‐ether‐ketone) composite film (NH 2 ‐MWCNTs&GnPs@PBO/PEEK, NH ‐MGPP) is fabricated using vacuum‐assisted filtration. As result, the ‐MGPP (0.05 mm thick) exhibited exceptional performance (71.47 dB) in‐plane (36.78 W m −1 K ). also demonstrated rapid Joule heating kinetics an efficient photothermal response, enabling effective management energy harvesting capabilities. When integrated into solar‐thermoelectric generator, produced output voltage 1004.9 mV under 5 kW −2 simulated sunlight irradiation, confirming its photo‐thermal‐electrical conversion efficiency. This study presents innovative approach designing developing films with excellent properties heat dissipation Additionally, it introduces new method utilization renewable energy.
