摘　　要：为了探索石墨烯(GP)纳米材料对丙烯腈-丁二烯-苯乙烯共聚物(ABS)微孔发泡注射泡孔形态演化规律,以ABS为基材,GP纳米材料为添加剂,采用微孔发泡注射工艺,制备不同GP含量的复合材料。探讨GP含量对ABS/GP复合材料的发泡形态的影响。结果表明:GP添加量的增加可以改善复合材料发泡形态,使气泡大小较均匀。但GP添加量超过3%,复合材料气泡形状受到GP挤压变得不规则。GP添加量为2%时,GP产生的团聚状况较少。ABS/2%GP复合材料的厚度比ABS/3%GP薄,说明GP的分散状况较好。X光衍射分析中,ABS/GP复合材料出现GP峰值,随着GP添加量的增加,GP峰值也越明显。In order to explore the morphological evolution of acrylonitrile-butadiene-styrene(ABS) microcellular foaming injection with graphene(GP) nanomaterials,the composites with different GP contents were prepared by the microcellular foaming injection process with ABS as the substrate and GP nanomaterials as additives.The effects of GP content on the foaming morphology of ABS/GP composites were discussed.The results show that the increase of GP content can improve the foam morphology of the composites and make the bubble size more uniform.However,when the content of GP exceeds 3%,the bubble shape of composites becomes irregular due to the GP extrusion.When the amount of GP is 2%,the agglomeration of GP is less.The thickness of ABS/2%GP composites is thinner than that of ABS/3%GP,which indicates that the dispersion of GP is better.In X-ray diffraction analysis,the peak value of GP appeared in ABS/GP composites,and the peak value of GP becomes more obvious with the increase of GP content.
