“…Many studies have demonstrated that constructing “bridge” structure between fillers/matrix or filler/filler through nanoparticles was another effective strategy to reduce the thermal resistance and increase the contact area to transport heat. Thus, AgNPs [ 52 , 141 ], copper nanowires [ 25 ], Cu microparticles [ 188 ], nanodiamond [ 148 ] and Al 2 O 3 nanoparticles [ 177 ] have been used as the “bridge” units to enhance the k of films. MD simulation also demonstrated that intimate contact and high overlap area can cause significant reduction in ITR [ 189 ].…”

Effective thermal management is quite urgent for electronics owing to their ever-growing integration degree, operation frequency and power density, and the main strategy of thermal management is to remove excess energy from electronics to outside by thermal conductive materials. Compared to the conventional thermal management materials, flexible thermally conductive films with high in-plane thermal conductivity, as emerging candidates, have aroused greater interest in the last decade, which show great potential in thermal management applications of next-generation devices. However, a comprehensive review of flexible thermally conductive films is rarely reported. Thus, we review recent advances of both intrinsic polymer films and polymer-based composite films with ultrahigh in-plane thermal conductivity, with deep understandings of heat transfer mechanism, processing methods to enhance thermal conductivity, optimization strategies to reduce interface thermal resistance and their potential applications. Lastly, challenges and opportunities for the future development of flexible thermally conductive films are also discussed.

The rapid development of electronic technology puts forward higher requirements for thermal management materials. In this paper, polydopamine (PDA) was employed to improve the interfacial interaction between filler and matrix, and then to further regulate the interfacial thermal resistance and thermal conductivity of ethylene-vinyl acetate (EVA) composites. It was found that boron nitride (BN) sheets and carbon nanotubes (CNTs) can fully exert the synergistic heat conduction effect with the assistance of PDA, and construct continuous and efficient heat conduction channels in EVA matrix. When 30 vol% BN and 2 vol% CNTs were added, the in-plane thermal conductivity of the composite reached 9.61 WÁm À1 ÁK À1 , which was about 3225% higher than that of EVA matrix. The contribution of PDA to auxiliary enhanced thermal conductivity was further verified by the fitting and calculation of the interfacial thermal resistance of the composites. In addition, the EVA composite material had sensitive thermal response and stable electrical insulation properties, which ensured its thermal management applications in electronic equipment.
