Sustainable High Thermal Conductivity Composites from Biomass: Bio-Based Polyimide/Microencapsulated CNTs for Green Thermal Management

Driven by the miniaturization and integration of electronic components, escalating thermal loads have necessitated the development of materials with high thermal conductivity. However, the direct incorporation of thermally conductive fillers (e.g., carbon nanotubes, CNTs) into polymer matrices often resulted in poor dispersion and interfacial compatibility, thereby limiting overall performance. In this study, a biobased polyimide (Bio-PI) was synthesized from 2,5-furandicarbonyl dichloride (FDCA-Cl2), a biobased FDCA derivative. Carboxyl-functionalized CNTs (c-CNTs) were engineered via SiO2 core–shell encapsulation and ODA modification to obtain surface-functionalized m-CNTs. During composite formation, in…
