摘　　要：通过原位聚合法制备了聚甲基丙烯酸甲酯(PMMA)/碳纳米管(CNTs)复合材料。分析了CNTs对PMMA制备工艺的影响;通过热失重分析研究了材料的热稳定性;通过锥形量热测试研究了材料的阻燃性能。CNTs的添加改变了聚合诱导期和体系的黏度,影响了复材制备的预聚合时间和聚合温度;TGA研究表明CNTs的加入提高了材料的热稳定性;燃烧试验表明CNTs的添加能够改善材料的燃烧特性。Polymethyl methacrylate(PMMA)/carbon nanotube(CNTs)composites were prepared via in-situ polymerization.The influ-ence of CNTs on the preparation process of PMMA/CNTs nano-composites was analyzed.The pyrolysis was characterized using thermal analysis.Flame retardancy was investigated with cone cal-orimeter.The addition of CNTs makes changes on the induction period of the poly merization and the viscosity of the system,which affects the prepoly merization time and polymerization tem-perature of the composites preparation process.TGA shows that adding CNTs can improve the thermal stability.Combustion exper-iments showed that adding CNTs can improve the combustion per-formance of the material.
