摘　　要：在二次开模注塑成型条件下制备了聚丙烯/氧化石墨烯(PP/GO)发泡复合材料,研究了GO用量对PP微发泡复合材料力学性能、结晶性能和发泡行为的影响。结果表明:GO加入PP发泡复合材料中,能够明显改善PP复合材料泡孔结构,提高其发泡质量;当GO用量为3份时,PP/GO发泡复合材料的发泡性能相对最好,其泡孔直径为24.8μm,泡孔密度2.5×10~8个/cm^3。The Polypropylene/grapheme oxide（PP/GO） foam composites were prepared under twice-open mold conditions. The effects of GO content on the mechanics properties, thermal performance and foaming behavior of PP/GO foam composites were studied. The results show that： the foaming structure of PP composites can be improved obviously by adding GO into PP foaming composites, and the foaming quality can be improved. When the amount of GO is 3 phr, the foaming property of PP/GO foam composite is the best, the bubble diameter is 24.8 μm, and the cell density is 2.5×10 8 cell/cm3.
