“…11,14,15,[50][51][52][53][54][55] Besides, CNTs can be functionalized and dispersed in some polymers for coating applications, 56 like typical CNT-filled epoxy-based nanocomposites. 57 Such a nanocomposite coating can bring about improved anti-corrosion ability in comparison with pure epoxy coating. However, the coating layer may encounter problems of peeling.…”

“…A large number of studies suggest that graphite is widely used as a flame retardant additive, which has an impact on the expansion performance and explosion resistance of fireresistant coatings 15 ; graphites also have the "candlewick effect" and "barrier effect". 16 Accordingly, carbonaceous material has been used as flame-retarding additive for designing halogen-free Si/C flame retardants including the multiwalled carbon nanotube, 17,18 due to charring and generating "barrier effect", but its high preparation cost is difficult to overcome. Therefore, flake graphite (FG) is selected to enhance the carbonization, compatibility, and expansion properties of silica fume-based coatings.…”

A facile design for value-added recycling of metallurgical solid waste is urgent for developing safe and sustainable human settlements. Therefore, novel DOPO/flake graphite (FG) co-doped silica fume-based geopolymer coatings for flame-retarding plywood were prepared to seek a halogen-free and low-carbon Si-C-P fireproof method. The results show that appropriate DOPO (1 wt%) constitutes an enhanced flame retardancy, evidenced by the reduced peak of heat release rate (decreases from 153.48 to 96.94 kW m À2 ) and the rising flame retardancy index (climbs from 1.00 to 2.32). Meanwhile, its pyrolysis is identified as the three-level chemical reaction model (F3), the hydrogen bond crosslinking between the P O C and HO Si O results in a rising E α at 1000-731 C (increases from 163.60 to 198.83 kJ mol À1 ). Finally, the synergistically flame-retardant mechanism consists of water volatilization at 100 C, the as-formed porous carbonaceous layer at about 200 C, transformations of DOPO at 300-500 C, the formed DOPO derivatives at 500-700 C, and the decomposition of DOPO derivatives (condensed phase barrier) above 700 C, respectively. The yielded residues generate a 56% formaldehyde adsorption rate. It proposes a halogen-free and low-carbon strategy for designing Si-C-P hybrid flame-retarding coatings, indicating an ecological direction for the value-added utilization of metallurgical solid waste.

“…[1][2][3][4][5] Epoxy resins have excellent electrical insulation properties, outstanding corrosion resistance, good dimensional and thermal stabilities, as well as high mechanical properties; these materials are widely used in the packaging of electronic devices. [6][7][8][9][10] However, they also exhibit low intrinsic thermal conductivity, owing to the amorphous arrangement of the epoxy molecular chains, which limits their application as thermally conductive materials. [11][12][13][14] N-Benzylpyrazinium hexafluoroantimonate (BPH) is a cationic thermally latent initiator of epoxy resins, which is inert at room temperature.…”

A silane coupling agent was used to modify the surface of expanded graphite (EG), which was subsequently used as a thermally conductive filler to fabricate diglycidylether of bisphenol-A (DGEBA)/EG composites with high thermal conductivity via hot blending and compression-curing processes. The surface characteristics of silane coupling agent-modified EG (Si@EG) were characterized by a variety of analytical techniques. The effects of the Si@EG content on the thermal conductivity, thermal stability, impact strength, and morphology of the DGEBA/Si@EG composites were investigated. The results revealed that the addition of 80 wt.% Si@EG increased the thermal conductivity of the composites from 0.17 to 10.56 W/m K, which was 61.1 times higher than that of pristine DGEBA. The initial decomposition temperature of the composite containing 80 wt.% Si@EG was 60.6 C higher than that of pristine DGEBA. The impact strength of the composites decreased from 2.0 to 0.87 kJ/m 2 when the Si@EG content increased from 0 to 80 wt.%. The scanning electron microscopy images of the fractured surfaces revealed that the EG sheets in the DGEBA matrix formed a continuous thermally conductive path at high Si@EG contents.
