“…[ 50 ] The comparison of the thermal conductivity of the four group of samples is shown in Figure 5A. The thermal conductivity of raw wood and WFC are only 0.099 [ 22 ] and 0.36 W m −1 K −1 , respectively. The thermal conductivity of WFC@hBN‐10, WFC@hBN‐15 and WFC@hBN‐20 are 0.54, 0.79, and 1.41 W m −1 K −1 , respectively.…”

“…The hBN powders (particle size of 3–5 μm, density of 2.27 g cm −3 ) were purchased from Hebei Metallurgical Research Institute (China). The source of the waste poplars (cut into 2–3 cm long sheets) was same as our previous literature, [ 22 ] while the NaOH used in the experiment was obtained from Sinopharm Chemical Re‐agent Co, Ltd. (China). Yituo Composites Co, Ltd. (China) supplied the accessories needed to assemble the VARTM device.…”

“…Two winding tubes were attached to the two edges of the slab, one for the infusion and the other for the outflow of epoxy resin. Epoxy resin was infused into WF@hBN using the VARTM process at a vacuum level of 0.1 MPa, and the vacuum was maintained for 1 h. [ 22 ] After the WF@hBN was fully impregnated with epoxy resin, it was hot‐pressed at 100°C for 1 h. After complete curing, different lignocellulosic composites were obtained, including WFC, WFC@hBN‐10, WFC@hBN‐15, and WFC@hBN‐20, which contained varying amounts of hBN (0/10/15/20 g).…”

“…Mechanical properties were tested using the methods in our previous literature. [ 22 ] The samples underwent thermogravimetric (TG) analysis using a TGA55 instrument from TA (United States). For TG analysis, approximately 10 mg of bone‐dry samples were ground to a powder of about 120 mesh and collected.…”

“…[19] In addition, novel multidimensional nanomaterials, such as carbon nanotubes and graphene, are also regarded as good thermally conductive fillers. [20][21][22][23][24] Due to its good thermal conductivity, boron nitride (hBN) is often used as a thermal filler to improve the thermal conductivity of polymers and composite materials. [25] The materials prepared in these ways still have defects such as complex process and high cost.…”

The high demand for thermally conductive materials in the housing and packaging industry of electronic device highlights the necessity for the development of novel thermal conductivity materials. In this study, waste poplar wood was delignified and combined with boron nitride (hBN) to establish a blend system with a cross thermally conductive network. Using the vacuum‐assisted resin transfer molding process, a biobased composite material was prepared with high thermal conductivity (1.41 W m−1 K−1), mechanical strength (flexural strength of 100.7 MPa and tensile strength of 40.0 MPa), flame retardancy, and water resistance. Compared with raw wood, the incorporation of hBN increased the thermal conductivity of the prepared material by 1324.2%. The high thermal conductivity performance surpassed that of most polymers and elastomers commonly used in electronic component heat dissipation materials, indicating the enormous potential of the prepared composite material in the field of heat dissipation materials.

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.

In light of the uprising global development on sustainability, an innovative and environmental friendly wood‐based material derived from natural pinewood has been developed as a high‐performance alternative to petrochemical‐based materials. The wood‐based functional material, named as BC‐CaCl2, is synthesized through the coordination of carboxyl groups (−COOH) present in pinewood with calcium ions (Ca2+), which facilitates the formation of a high‐density cross‐linking structure through the combined action of intermolecular hydrogen bonds. The as‐prepared BC‐CaCl2 exhibits excellent tensile strength (470.5 MPa) and flexural strength (539.5 MPa), establishing a robust structural basis for the materials. Meanwhile, BC‐CaCl2 shows good water resistance, thermal conductivity, thermal stability, UV resistance, corrosion resistance, and antibacterial properties. BC‐CaCl2 represents a viable alternative to petrochemical‐based materials. Its potential application areas include waterproof enclosure structure of buildings, indoor underfloor heating, outdoor UV resistant protective cover, and anti‐corrosion materials for installation engineering, and so forth.image
