摘　　要：通过将二甲基-2-(丙烯酰氧乙基)磷酸酯(DMMEP)聚合接枝至苎麻纤维表面实现两种材料的有效结合,并采用FTIR方法确定其化学结构,研究其表面形貌及对苎麻纤维阻燃性能的影响。结果表明,DMMEP的引入使得苎麻纤维在高温下的热稳定性能提高,表现为燃烧结束时纤维的残炭量显著增加,并较好的保留了苎麻的原始形貌。化学接枝纤维在提高阻燃性的能尽量保持纤维的原始性能,有望大规模应用于特殊领域。The graft polymerization of dimethyl-2-(acryloyloxyethyl)phosphate(DMMEP)onto the surface of ramie fiber has been prepared.The FTIR and SEM methods are used to investigate its chemical structure and surface morphology.The TG analysis shows that the introduction of DMMEP improves the thermal stability of ramie fiber at high temperature.The LOI test demonstrats that the residual carbon content of the fiber increased after combustion and the original morphology of ramie is preserved perfectly.The chemical grafting of fibers which can improve the flame retardant properties and maintain the original performance of the fiber is expected to applicate in special areas.
