“…Conventional thermal insulation materials are mainly divided into foam-based materials [5], phase change materials [6] and ceramic aerogel materials [7]. Among them, foam-based thermal insulation materials have defects such as low ignition point and release of toxic substances during combustion.…”

A lightweight flexible thermally stable composite is fabricated by combining silica nanofiber membranes (SNM) with MXene@c-MWCNT hybrid film. The flexible SNM with outstanding thermal insulation are prepared from tetraethyl orthosilicate hydrolysis and condensation by electrospinning and high-temperature calcination; the MXene@c-MWCNTx:y films are prepared by vacuum filtration technology. In particular, the SNM and MXene@c-MWCNT6:4 as one unit layer (SMC1) are bonded together with 5 wt% polyvinyl alcohol (PVA) solution, which exhibits low thermal conductivity (0.066 W m−1 K−1) and good electromagnetic interference (EMI) shielding performance (average EMI SET, 37.8 dB). With the increase in functional unit layer, the overall thermal insulation performance of the whole composite film (SMCx) remains stable, and EMI shielding performance is greatly improved, especially for SMC3 with three unit layers, the average EMI SET is as high as 55.4 dB. In addition, the organic combination of rigid SNM and tough MXene@c-MWCNT6:4 makes SMCx exhibit good mechanical tensile strength. Importantly, SMCx exhibit stable EMI shielding and excellent thermal insulation even in extreme heat and cold environment. Therefore, this work provides a novel design idea and important reference value for EMI shielding and thermal insulation components used in extreme environmental protection equipment in the future.

“…As a promising potential candidate, phase change materials (PCMs) have the advantages of low cost, high latent heat, and easy manufacture, which could absorb or release a large amount of heat during the phase change process . The research on the application of PCM-based energy storage systems for power peaking, solar energy utilization, and green building energy efficiency has developed rapidly. − Among PCMs, organic solid–liquid phase change materials have become the main raw material source of PCMs because of their corrosion resistance, safety, nontoxicity, good chemical durability, practically no supercooling, and so on . However, organic solid–liquid PCMs typically exhibit poor thermal conductivity and serious leakage issues .…”

Phase change energy storage technology provides a viable option for the use of solar energy; however, its potential shortcomings such as low thermal conductivity, phase change leakage, and fire hazards have led to defective applications. In this paper, graphene/boron nitride (GB) aerogels with dual thermal conductivity networks are constructed using boron nitride precursors BM (boric acid and melamine) and graphene oxide through a self-assembly method during reduction and calcination. The GB aerogels are then vacuum impregnated with paraffin wax (PW) to prepare PW−GB composite phase change materials (PCMs). The results show that the dual-layer network structure ensures that the PW−G 4 B 2 composites have outstanding latent efficiency (96.7%) as well as a low leakage rate of 3.0%. Thanks to the highly thermally conductive BN fiber attachment, the thermal conductivity of PW−GB reaches 0.4108 W/(m•K), which is 81.5% higher than that of pure PW. Meanwhile, its photothermal conversion efficiency reaches 78.99% at 100 mW/cm 2 optical density, showing great potential for thermal management in photothermal conversion applications. Moreover, the synergistic barrier effect of BN fibers with excellent thermal stability and graphene nanosheets results in significant improvements in the thermal stability and flame-retardant performance.
