“…Shtein et al developed graphene‐based hybrid composites with up to 90% reduced thermal resistances after the addition of a secondary ceramic‐based filler. Novel polymer composites consisting of graphene foam/carbon black/polydimethylsiloxane or graphene oxide/poly (vinylidene fluoride)/CNTs were also shown to greatly enhance the TC.…”

With the development of energy science and electronic technology, interfacial thermal transport has become a key issue for nanoelectronics, nanocomposites, energy transmission, and conservation, etc. The application of thermal interfacial materials and other physical methods can reliably improve the contact between joined surfaces and enhance interfacial thermal transport at the macroscale. With the growing importance of thermal management in micro/nanoscale devices, controlling and tuning the interfacial thermal resistance (ITR) at the nanoscale is an urgent task. This Review examines nanoscale interfacial thermal transport mainly from a theoretical perspective. Traditional theoretical models, multiscale models, and atomistic methodologies for predicting ITR are introduced. Based on the analysis and summary of the factors that influence ITR, new methods to control and reduce ITR at the nanoscale are described in detail. Furthermore, the challenges facing interfacial thermal management and the further progress required in this field are discussed.

“…The fact that polymerbased materials have low thermal conductivity (less than 10 W/m K even for most of the composite materials with high thermal conductivity fillers) (Ref [80][81][82][83][84] suggests that the non-dimensional parameter of time (t*) may also be smaller than 0.25 for many spray conditions on polymerbased materials. This may allow for the determination of the temperature distribution within polymeric substrates during the thermal spray metallization process by using the graph presented in Fig.…”

A literature review on the thermal spray deposition of metals onto polymer-based structures is presented. The deposition of metals onto polymer-based structures has been developed to enhance the thermal and electrical properties of the resulting metal-polymer material system. First, the description of the thermal spray metallization processes and technologies for polymer-based materials are outlined. Then, polymer surface preparation methods and the deposition of metal bond-coats are explored. Moreover, the thermal spray process parameters that affect the properties of metal deposits on polymers are described, followed by studies on the temperature distribution within the polymer substrate during the thermal spray process. The objective of this review is devoted to testing and potential applications of thermal-sprayed metal coatings deposited onto polymer-based substrates. This review aims to summarize the state-of-the-art contributions to research on the thermal spray metallization of polymer-based materials, which has gained recent attention for potential and novel applications.

“…Due to its high thermal stability, good mechanical properties and low dielectric constant, polydimethylsiloxane (PDMS) has been widely investigated as thermal interface materials. However, its TC is 0.1–0.2 Wm −1 K −1 at room temperature , which cannot meet the heat dissipation requirements of modern electronic components and electrical systems. Its low TC is attributed to the random orientation of molecular chains, leading to the reduction of the mean free path of heat conducting phonons .…”

Graphite tube woven fabrics (GTWF) and boron nitride (BN) sheets filled polydimethylsiloxane (PDMS) composites were successfully prepared with enhanced thermal conductivity (TC) and electrical insulation. The continuous graphite tubes after etching nickel template provide fast channels for heat transfer, especially in in‐plane direction. The addition of BN prevents the formation of electrically conductive networks in the matrix. GTWF/BN/PDMS composites exhibit synchronously good TC and relatively high electrical resistivity. When compared with PDMS, the TC of GTWF/BN/PDMS composite with 4.2 wt% GTWF and 14 wt% BN is increased by 166 and 2521% in out‐of‐plane and in‐plane directions, respectively. Meanwhile, its electrical insulation is also improved compared with GTWF/PDMS composites. All above properties provide advantages to the GTWF/BN/PDMS composite for potential application in electronic packaging and electrical insulation. POLYM.
