“…They were considered to overcome many weaknesses of traditional thermal conducting polymers and are widely used as thermal interface materials [ 6 , 7 , 8 , 9 , 10 ]. Polydimethylsiloxane (PDMS) is often used as the matrix material of thermal interface materials because of its excellent properties, such as flexibility, low cost, chemical inertness, water resistance, and flame retardant [ 10 , 11 , 12 , 13 , 14 ]. However, the intrinsic thermal conductivity of PDMS (about 0.2 W·m −1 ·K −1 ) is not ideal to meet the needs of the electronic industry [ 15 , 16 , 17 , 18 , 19 ].…”

In this work, polydimethylsiloxane (PDMS)-based composites with high thermal conductivity were fabricated via a three-dimensional hybrid boron nitride@silver nanowires (BN@AgNWs) filler thermal network, and their thermal conductivity was investigated. A new thermal conductive BN@AgNWs hybrid filler was prepared by an in situ growth method. Silver ions with the different concentrations were reduced, and AgNWs crystallized and grew on the surface of BN sheets. PDMS-based composites were fabricated by the BN@AgNWs hybrid filler added. SEM, XPS, and XRD were used to characterize the structure and morphology of BN@AgNWs hybrid fillers. The thermal conductivity performances of PDMS-based composites with different silver concentrates were investigated. The results showed that the thermal conductivity of PDMS-based composite filled with 20 vol% BN@15AgNWs hybrid filler is 0.914 W/(m·K), which is 5.05 times that of pure PDMS and 23% higher than the thermal conductivity of 20 vol% PDMS-based composite with BN filled. The enhanced thermal conductivity mechanism was provided based on the hybrid filler structure. This work offers a new way to design and fabricate the high thermal conductive hybrid filler for thermal management materials.

“…Metal has been widely studied to improve its thermal conductivity due to its inherent properties. So far, Ag [ 54 , 55 ], Cu [ 56 ] and Ni [ 57 ] are the three most commonly used metals to enhance the thermal conductivity of composite polymers. Huang et al [ 58 ] prepared ferroelectric polymer nanocomposites composed of poly(vinylidene fluoride) and Ag nanoparticles.…”

The boosting of consumer electronics and 5G technology cause the continuous increment of the power density of electronic devices and lead to inevitable overheating problems, which reduces the operation efficiency and shortens the service life of electronic devices. Therefore, it is the primary task and a prerequisite to explore innovative material for meeting the requirement of high heat dissipation performance. In comparison with traditional thermal management material (e.g., ceramics and metals), the polymer-based thermal management material exhibit excellent mechanical, electrical insulation, chemical resistance and processing properties, and therefore is considered to be the most promising candidate to solve the heat dissipation problem. In this review, we summarized the recent advances of two typical polymer-based thermal management material including thermal-conduction thermal management material and thermal-storage thermal management material. Furtherly, the structural design, processing strategies and typical applications for two polymer-based thermal management materials were discussed. Finally, we proposed the challenges and prospects of the polymer-based thermal management material. This work presents new perspectives to develop advanced processing approaches and construction high-performance polymer-based thermal management material.

“…Since Dikin et al [15] used membrane filters to prepare an ultra-strong graphene oxide paper for the first time in 2007, and vacuum filtration has widely been used in academic research. Many researchers prepared cellulose nanofiber/graphene-based composite film via vacuum filtration in recent years [16][17][18][19][20]. In the electrical shielding application, where electrical insulating materials are required, the excellent electrical conductivity of graphene has become an inevitable obstacle to its application [21].…”

Graphene-based film attracts tremendous interest in many potential applications due to its excellent thermal, electrical, and mechanical properties. This review focused on a critical analysis of fabrication, processing methodology, the interfacial modification approach, and the applications of this novel and new class material. Strong attention was paid to the preparation strategy and interfacial modification approach to improve its mechanical and thermal properties. The overview also discussed the challenges and opportunities regarding its industrial production and the current status of the commercialization. This review showed that blade coating technology is an effective method for industrial mass-produced graphene film with controllable thickness. The synergistic effect of different interface interactions can effectively improve the mechanical properties of graphene-based film. At present, the application of graphene-based film on mobile phones has become an interesting example of the use of graphene. Looking for more application cases is of great significance for the development of graphene-based technology.
