“…TPU is a copolymer consisting of both hard and soft segments. Its properties are mainly determined by the monomers, such as the type and crystallinity and copolymer morphologies of hard and soft segments [ 19 , 20 , 21 ]. The hard section has a direct effect on the mechanical properties of TPU, such as tensile strength, hardness, and modulus; the soft segment determines the elasticity and low temperature resistance of the TPU.…”

“…Previous studies have shown that graphene can not only strengthen and toughen TPU, but also improve the properties of TPU, such as wear resistance, scratch resistance, heat resistance, aging resistance, electromagnetic shielding property, etc. [ 6 , 9 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ]. The distribution of graphene sheets in TPU and their binding state affect the curing behavior of TPU, which affects electrical and thermal properties and microstructures of the composite films [ 20 , 21 , 22 , 23 ].…”

“…Polyurethane is a kind of block polymer composed of hard and soft segments, which has high industrial value and research value due to its excellent oil resistance, abrasion resistance, stretchability and so on [ 17 ]. Thermoplastic polyurethane (TPU), as an important branch of polyurethane, shows potential for use in the preparation of perforated membrane because of its excellent tensility, good elastic resilience, and excellent biocompatibility [ 18 , 19 , 20 , 21 ]. However, due to its poor electrical conductivity and thermal conductivity, it is difficult to further expand its application fields [ 19 , 22 ].…”

Graphene-thermoplastic polyurethane (G-TPU) composite films were fabricated by traditional blending method and tape casting process with commercial graphene sheets as functional fillers and TPU masterbatches of four different melting points as matrix, respectively. The effects of matrix on the distribution of graphene, the electrical conductivity, and infrared (IR) light thermal properties of the G-TPU composite films were investigated. The experimental results reveal that the characteristics of TPU has little influence on the electrical conductivity of the G-TPU composite films, although the four TPU solutions have different viscosities. However, under the same graphene mass content, the thermal conductivity of four G-TPU composite films with different melting points is significantly different. The four kinds of G-TPU composite films have obvious infrared (IR) thermal effect. There is little difference in the temperatures between the composite films prepared by TPU with melting a point of 100 °C, 120 °C, and 140 °C, respectively; however, when the content of graphene is less than 5 wt%, the temperature of the composite film prepared by TPU with a melting point of 163 °C is obviously lower than that of the other three composite films. The possible reason for this phenomenon is related to the structure of TPU.

“…Lin et al 130 improved the performance of Gr composite TIMs by using the modified Hummers' method by introducing SR polymers with a combination of acrylamide‐modified RGO (AA‐RGO) and thiophenol‐modified silver NWs (mAgNWs). The combination of these two additives enhanced the properties of the material given their different dimensions and, ultimately, the production of a 3D network structure.…”

Summary Thermal interface materials (TIMs) are applied in electronic devices that are involved in heat generation and raising the temperature. The optimization of TIMs is important in heat dissipation to maintain the good performance of devices, low power during operation, and reduced internal damages among small components. The TIMs are inserted between two contact surfaces to enhance thermal conductivity that will reduce the increment of surface temperature in a longer time and facilitates the cooling process with a consistent power supplied to the system with minimum increment. Research on nanomaterials and hybrid materials aims to obtain maximum thermal conductivity and reduce resistance in the devices. However, the suitable fabrication method for achieving good production and performance is still debatable. Therefore, significant fabrication methods have been explored for various materials. This review provides insights into the current work focusing on the materials used in the development of TIMs by various methods. The discussion begins with the introduction of thermal management and the working principles applied in the system. Then, the methods applied for material fabrication into TIMs, including the advantages and disadvantages of the methods, are discussed. Last, the current challenges and opportunities in methods used are discussed to offer new inputs and improvement in method modification for TIMs design. The targeted thermal performance for the industrial market of TIMs for nanomaterial applications is approximately 100 W/mK and 1 × 10−6 m2/WK with lowest power of 100 W.
