三维泡沫状石墨烯/乙丙橡胶复合材料的制备及其性能
Preparation and properties of three-dimensional graphene foam/ethylene propylene rubber composites
摘要
Abstract
In order to improve the mechanical properties of ethylene propylene rubber(EPR),large size three-dimensional graphene foam(GF)was prepared by hydrothermal reaction of graphene oxide.A certain amount of EPR chloro-form solution was poured into different amount of GF,and the solvent was evaporated and dried.Then the GF/EPR composites with different mass fraction was prepared by cold pressing and twin screw extruder.The structure of GF and composite were characterized by scanning electron microscopy(SEM)and transmission electron mi-croscopy(TEM).In addition, the effects of GF addition and different processing methods on the mechanical properties of the composite was investigated. Results indicated that GF can improve the tensile strength of the composites.When the content of GF is less than 1%,the tensile strength and elongation at break of the material prepared by the cold press increase significantly.Among them,the content of GF is 0.5%,the tensile strength of composite materials increased by 1.9 times, and its elongation at break also increased by 28.6%. Through the blending of twin screw extruder,the composites with the addition of GF≥5% have higher tensile strength,but the tensile strength and elongation at break of the composites with the addition of GF≤3% decreased a lot.关键词
