However, traditional filler-reinforced PEEK composites often struggle to achieve the desired thermal conductivity due to filler agglomeration resulting in high interfacial thermal resistance (ITR). To address these issues, laminated (NH<sub>2</sub>-GnPs&MWCNTs)/PEEK composite films were fabricated by electrostatic spraying technique and hot pressing process, with hybrid fillers that interconnected to form a compact heat-conducting network.
