摘要以可膨胀石墨为原料，采用微波加热法和熔融共混法成功制备了石墨烯/HDPE复合材料.运用扫描电子显微镜（SEM）、差示扫描量热仪（DSC）、X-射线衍射仪（XRD）和拉伸测试等方法对其性能进行表征.结果表明：厚片石墨烯（TSG）与HDPE基体具有良好的相容性；同时片层结构的石墨烯为HDPE结晶提供异相成核剂，使其结晶度提高；当加入的TSG质量分数为0.3%时，HDPE拉伸强度由22.5 MPa提升到24.9 MPa，提升了10.7%，弯曲模量由443.5 MPa提升到510.4MPa，提升了15.1%，冲击强度由55.3 kJ/m²提升到56.0 kJ/m²，提升了1.3%，明显提高了复合材料力学性能.

石墨烯高密度聚乙烯共混法复合材料增强

Abstract:

In this paper,the expandable graphite was used as raw material,and the graphene /HDPE composites were successfully prepared by microwave heating and melt blending.The properties were characterized by scanning electron microscopy(SEM),differential scanning calorimetry(DSC),X-ray diffractometry(XRD)and tensile test.The results show that thick graphene(TSG)has good compatibility with HDPE matrix.At the same time,graphene with lamellar structure provides heterogeneous nucleating agent for HDPE crystallization,which improves its crystallinity.When the mass fraction of TSG content was 0.3%,the HDPE tensile strength increased from 22.5 MPa to 24.9 MPa,increased by 10.5%,the bending modulus increased from 443.5 MPa to 510.4 MPa,increased by 15.1%,and the impact strength increased from 55.3 kJ/m²to 56.0 kJ/m²,increased by 1.3%.The mechanical properties of the composites are obviously improved.
