“…With the rapid development of the microelectronic technique towards higher packing and power density, thermal conductivity composites are playing an increasingly decisive role in the heat dissipation and lifespan extension of devices. [1][2][3][4][5][6][7] Polyurethane (PU)-based thermal conductivity composite has aroused deep concern due to its high mechanical properties. 8 However, one of the problems of PU is the petroleum feedstock, which leads to the depletion of fossil resources and aggravation of environmental problems.…”

With the miniaturization, high frequency of electronic devices, and low‐carbon and sustainable development, higher requirements are put forward for thermal conductive polyurethane composites in terms of comprehensive performance and renewable raw materials. Herein, choosing bio‐based polyurethane (PU) derived from castor oil as matrix, and liquid metal (LM) and aluminum hydroxide (ATH) as hybrid thermal conductive filler, castor oil‐based PU composites were developed via high‐speed rotation and in‐situ polymerization method. The LM‐ATH hybrid filler displayed a synergistic enhancement effect on the thermal conductivity of composites due to the presence of LM‐bridging significantly improved the effective contact probability between ATH fillers. The thermal conductivity of 50LM‐ATH/PU reached 1.69 Wm−1 K−1, which was 9.9 times and 1.4 times higher than that of pure PU and 50ATH/PU, respectively. Notably, the 50LM‐ATH/PU exhibited outstanding mechanical properties including tensile strength up to 4.0 MPa and adhesion strength up to 7.9 MPa, especially elongation at break up to 120% which was improved by 200% compared with 50ATH/PU (40%). Additionally, the composite possessed excellent electric insulation, thermal stability, and inflaming retarding properties, showing great application potential in the electronic devices field.Highlights Castor oil‐based PU composites with ATH‐LM hybrid filer were developed. LM‐ATH hybrid filler of 2:8 promoted the thermal conductivity of composites. Hybrid filler than ATH‐endowed composites with better mechanical properties. The ATH‐LM/PU exhibited excellent electric insulation.

Recently, MXene has been identified as a novel reinforcing material for elastomers. Also, the free radical scavenging ability of MXene can be used to improve the antiaging properties of unsaturated elastomers, such as natural rubber (NR). In this study, Ti3C2Tx MXene is incorporated into NR at 0‐0.8 wt% to investigate the mechanical and antiaging properties of NR/MXene nanocomposites (NRMX). The resultant nanocomposites with increasing MXene content show improved tensile properties and storage modulus due to the homogeneous distribution of MXene in the nanocomposite, interfacial interaction between MXene and NR molecules, and immobilization of NR polymer chains by MXene. Also, the reduced permanent deformation and hysteresis indicate a lowered heat build‐up with increasing MXene concentration. Finally, the improved mechanical properties retention, increased glass transition temperature, and reduced free radical, ‐OH, and C=O formation upon accelerated aging confirm the enhancement of the antiaging properties of NRMX nanocomposites.This article is protected by copyright.

The challenges associated with heat dissipation in high‐power electronic devices used in communication, new energy, and aerospace equipment have spurred an urgent need for high‐performance thermal interface materials (TIMs) to establish efficient heat transfer pathways from the heater (chip) to heat sinks. Recently, emerging 2D materials, such as graphene and boron nitride, renowned for their ultrahigh basal‐plane thermal conductivity and the capacity to facilitate cross‐scale, multi‐morphic structural design, have found widespread use as thermal fillers in the production of high‐performance TIMs. To deepen our understanding of 2D material‐based TIMs, in this review, we focus primarily on graphene and boron nitride‐based TIMs, exploring their structures, properties, and applications. Building on this foundation, we emphasize the developmental history of these TIMs and provide a detailed analysis of critical challenges and potential solutions. Additionally, we briefly introduce the preparation and application of some other novel 2D materials‐based TIMs, aiming to offer constructive guidance for the future development of high‐performance TIMs.This article is protected by copyright.
