摘　　要：采用熔融共混法制备了聚环氧乙烷(PEO)/埃洛石纳米管(HNTs)复合材料,重点研究了HNTs含量对PEO/HNTs复合材料的微观结构、热稳定性及燃烧性质的影响。结果表明,在熔融共混条件下,不同含量的表面未经任何处理的HNTs以纳米尺度均匀分散于PEO基体中;随着HNTs含量的增加,复合材料的热稳定性显著增加。氧指数和水平燃烧测试结果均表明随着HNTs含量的增加,复合材料的阻燃能力有较大提高。Poly（ethylene oxide）（PEO） / halloysite nanotubes（HNTs） composites were prepared by melt blending,and the microstructure,thermal stability and flame retardant effects of HNTs content on PEO composites were investigated.The results showed that different content HNTs without any surface modification were dispersed in PEO matrix evenly at nanoscale.Thermal stability of the nanocomposites was found remarkably enhanced by the incorporation of HNTs.Oxygen index and horizontal burning rate also showed the decrease of flammability of the nanocomposites with increasing of HNTs content.
