Schematic diagrams of mechanism of interfacial optimization. Schematic diagrams of blocked heat flow, severe phonon scattering, and high ITR at the interfaces in rGO/PI thermally conductive composite films (a). Schematic diagrams of smooth heat flow, reduced phonon scattering, and low ITR at the interfaces in NH2-rGO/PI thermally conductive composite films (b).
