“…There are two main methods to reduce the electrical resistivity of materials: adding an antistatic agent and external coating. Yan et al added functional material PPMPPE to an EVA matrix to explore the effect of additives on the flame retardancy and mechanical properties of EVA [ 2 ]. The results show that the flame retardancy of EVA had been greatly improved, and its mechanical properties were well maintained.…”

As a common coal-based solid waste, fly ash is widely used in material filling. However, due to the high resistivity of fly ash itself, the antistatic performance of the filling material is poor. Therefore, antistatic composite powder was prepared by coating nano-sized antimony-doped tin oxide (ATO) on the surface of fly ash, and its preparation mechanism was discussed. The composite powders were characterized by SEM, EDS, XRD and FTIR. The results show that the interaction between SiO2 and SnO2 appears at the wave number of 727.12 cm−1, and the obvious SnO2 crystal phase appears on the surface of fly ash. The volume resistivity of calcined fly ash is 1.72 × 1012 Ω·cm, and the volume resistivity of ATO fly ash is reduced to 6 × 103 Ω·cm. By analyzing the limiting oxygen index, melt index, tensile strength, elongation at break, cross-section morphology and surface electrical resistivity of EVA, it was found that the addition of antistatic powder to EVA can improve its antistatic performance without deteriorating the mechanical properties of EVA.

The enhancement of flame resistance and mechanical strength is critical for the utilization of rigid polyurethane foam (RPUF) composites. In this study, the efficient synergistic flame‐retardant system, incorporating dimethyl methylphosphonate (DMMP) and expandable graphite (EG), with the addition of refined alkali lignin (A‐lignin) were aimed to superior fire resistance and mechanical integrity for RPUF. Furthermore, the flame retardancy and charring ability of obtained RPUF were obviously enhanced. Notably, an RPUF mixture containing A‐lignin, DMMP, and EG demonstrated substantial charring at elevated temperatures, improved limiting oxygen index, and met the UL‐94 V‐0 rating. Cone calorimeter test indicated that this formulation produces less heat and smoke than pure RPUF. The flame‐retardant efficacy of obtained RPUF was attributed to the formation of a protective char layer coupled with the free radical neutralization properties of DMMP, collectively enhancing the flame retardancy obtained RPUF. Additionally, this RPUF variant showed significant advancements in both mechanical and thermal performance. This study outlines a successful strategy for developing RPUF composites endowed with enhanced flame retardancy and mechanical strengths.

Two‐dimensional molybdenum disulfide (MoS2) nanosheets are promising nanofillers for improving the properties of polymers, but low‐cost, facile and green methods need to be further explored to meet the requirements for large‐scale production of modified MoS2 nanosheets. Here, we developed a new idea that is, to prepare MoS2@Ag by modifying the surface of MoS2 using radiative reduction. It is noteworthy that the modified MoS2@Ag can effectively improve the mechanical strength of ethylene‐vinyl acetate (EVA) composites. In addition, the addition of MoS2@Ag was able to substantially improve the flame‐retardant properties of EVA, resulting in a significant reduction in the amount of heat and smoke released from its combustion. When two parts of MoS2@Ag were added, the peak heat release rate and total smoke release of EVA/2.0MoS2@Ag composites were reduced by 29.7% and 39.2%, respectively, compared with that of pure EVA. At the same time, the toxic gases (e.g., CO) produced by the combustion of EVA composites were significantly reduced, which indicates an improvement in their fire safety.
