With the rapid advancement of artificial intelligence, smart sensing technologies, and batteries with high power density, thermal management has become a critical issue for electronic devices. Phase change materials (PCMs) offer promising applications in management. However, it is significant challenge to fabricate PCMs conductivity (TC) electromagnetic interference shielding effectiveness (EMI SE) while maintaining leakage-free performance. This work reports solid–solid phase composites TC EMI SE enabled by covalent functionalization quasi-hyperbolic framework. The material (OP) synthesized via nucleophilic ring-opening reaction epoxy groups, where octadecanol (OD) grafted onto side chains polyethylene-co-methyl acrylate-co-glycidyl methacrylate (PEMAGMA). Subsequently, filled into electrochemically expanded graphite (EEG) framework through vacuum filtration, which EEG produced using an electrochemical expansion method SE. obtained OP/EEG exhibited excellent properties, including very low leakage (0.6%), latent heat (86.45 J/g), ultrahigh (22.6 W/(m·K)), superior (110.28 dB). shows great potential improving transfer efficiency interface (TIMs) practical applications, demonstrating outlook field
