摘　　要：为提高涤纶(PET)织物的阻燃性能,以水热还原自组装的方法制备石墨烯气凝胶(GA)阻燃PET织物。采用扫描电镜对GA的微观形貌进行分析,并对构建工艺参数进行探讨以优化其结构。通过极限氧指数(LOI)、锥形量热仪等方法分析GA的结构对PET织物阻燃性能的影响。研究结果表明,GA/PET织物的最佳制备工艺条件为氧化石墨烯(GO)浓度为5 mg/mL、GO与抗坏血酸的质量比为1:6、还原温度为100℃;当GA含量为26.3%时,GA/PET织物的LOI值高达32.1%,达到难燃材料的级别,且具有良好的抑烟效果,可作为一种新型碳材料应用于阻燃织物领域。In order to improve the flame retardant properties of polyester(PET)fabrics,graphene aerogel(GA)flame retardant PET fabrics were prepared by hydrothermal reduction self-assembly method.Scanning electron microscopy was used to analyze the microstructure of GA,and the construction process parameters were discussed to optimize its structure.The effects of GA structure on the flame retardancy of PET fabrics were analyzed by limiting oxygen index(LOI)and cone calorimeter.The results show that,the optimal preparation process conditions for GA/PET fabrics are as follows:the concentration of graphene oxide(GO)is 5 mg/mL,the mass ratio of GO to ascorbic acid is 1 to 6,and the reduction temperature is 100℃.When the GA content is 26.3%,the LOI value of GA/PET fabrics is as high as 32.1%,reaching the level of flame-retardant material,and the smoke suppression effect is achieved.It can be used as a new type of carbon material in the field of flame-retardant fabrics.
