| 摘 要： | 综述了近几年来乙烯-乙酸乙烯酯共聚物/多壁碳纳米管（EVA/MWNTs）纳米复合材料的研究进展，介绍了其制备方法，详述了其热解行为及阻燃性能（包括热释放速率、引燃时间、成炭性），并对其阻燃机理进行了深入的讨论。比较了MWNTs、有机黏土、层状双氢氧化物等不同纳米填料的阻燃性能，分析了对MWNTs进行不同处理（包括纯化、使用高密度聚乙烯进行表面涂覆改性、研磨）对相应纳米复合材料的热稳定性及可燃性的影响。

| Abstract: | Recent studies on ethylene vinyl acetate copolymer (EVA)/multi-walled carbon nanotubes (MWNTs) nanocomposites have been reviewed. A detailed introduction was given on its preparation, thermal degradation behavior, and flame retardant properties such as heat release rate, time to ignition, and char formation performance. The fire resistant mechanisms have been discussed in depth. The flame retardant effects of different nanofillers like MWNTs, organoclay, and layered double hydroxides have been compared. And the influence of various treatments of MWNTs, such as purification, surface coating with high density polyethylene, and ball milling, on the thermal stability and flammability of the corresponding EVA nanocomposites have been analyzed. |
