Effect of Graphene Content on Cell Morphology of Microcellular Foams
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.
