“…It is worth noting that the bioSiC/EP composite could maintain its initial shape after burning for 180 s (Figure 9h), which is due to the densely interconnected 3D bioSiC structure stabilizing the whole framework of the composite. [90][91][92] Combined with infrared thermal images (Figure 9c,f,i), the pure EP showed obvious deformation after burning for 30 s, however, the random SiC/EP and bioSiC/EP composites could maintain its initial shape. In addition, the surface temperature of bioSiC/EP composite is higher than the random SiC/EP composite at the same combustion time (60 s), indicating that the heat transfer is faster in the bioSiC/EP composite.…”

Construction of a vertically aligned and densely interconnected ordered 3Dfiller framework in a polymer matrix is a challenge to attain significant thermal conductivity (TC) enhancement efficiency. Fortunately, many biomaterials with unique microstructures can be found in nature. With inspiration from wood, artificial composites can be rationally designed to achieve desired properties. Herein, the authors report a facile and effective approach to fabricate anisotropic polymer composites by biotemplate ceramization technology and subsequent vacuum impregnation of epoxy resin. The hierarchical microstructure of wood is perfectly replicated in the cellular biomass derived SiC (bioSiC) framework by carbothermal reduction. Owing to the anisotropic architecture of bioSiC, the epoxy composite with vertically aligned dense SiC microchannels shows interesting properties, including a high TC (10.27 W m −1 K −1 ), a significant enhancement efficiency (259 per 1 vol% loading), an outstanding anisotropic TC ratio (5.77), an extremely low coefficient of linear thermal expansion (12.23 ppm K −1 ), a high flexural strength (222 MPa), and an excellent flame resistance. These results demonstrate that this approach is expected to open a new avenue for design and preparation of high performance thermal management materials to address the heat dissipation of modern electronics.

Epoxy resin (EP) has featured many industrial and practical applications, but was plagued by its inherent flammability. Herein, a hybrid flame retardant (mSiO 2 @TETP) was fabricated by in-situ immobilizing tin ethylenediamine tetramethylene phosphonate (TETP) on the mesoporous silica (mSiO 2 ) surface, and was used to prepare mechanical-robust, flame-retardant, and thermal-resistant EP composites. It is found that the introduction of only 1.0 wt% mSiO 2 @TETP into EP leads to a 20.5%, 19.7%, and 12.8% incremental tensile modulus, tensile strength, and impact strength, respectively. The EP composite with 5.

Epoxy resins are thermosets with interesting physicochemical properties for numerous engineering applications, and considerable efforts have been made to improve their performance by adding nanofillers to their formulations. MXenes are one of the most promising functional materials to use as nanofillers. They have attracted great interest due to their high electrical and thermal conductivity, hydrophilicity, high specific surface area and aspect ratio, and chemically active surface, compatible with a wide range of polymers. The use of MXenes as nanofillers in epoxy resins is incipient; nevertheless, the literature indicates a growing interest due to their good chemical compatibility and outstanding properties as composites, which widen the potential applications of epoxy resins. In this review, we report an overview of the recent progress in the development of MXene/epoxy nanocomposites and the contribution of nanofillers to the enhancement of properties. Particularly, their application for protective coatings (i.e., anticorrosive and friction and wear), electromagnetic-interference shielding, and composites is discussed. Finally, a discussion of the challenges in this topic is presented.
