| 摘 要： | 为研究氧化石墨烯对聚酰胺6的相容性和力学性能的影响,以天然鳞片石墨为原料,采用改良的Hummers方法制备氧化石墨烯,用氯化亚砜将其活化得到酰氯修饰氧化石墨烯,再与氨气反应制备氨基化氧化石墨烯,采用原位聚合法制备出聚酰胺6/氧化石墨烯复合材料,利用扫描电子显微镜对其进行表征分析,通过在甲酸中的分散实验研究该材料的相容性,并利用拉伸实验测试其力学性能.结果表明:聚酰胺6成功以化学键形式键接到氨基化氧化石墨烯表面;氧化石墨烯在聚酰胺6基体中呈现均匀稳定分散;氧化石墨烯均匀分散于甲酸中,其在甲酸中的相容性得到了明显改善;氨基化氧化石墨烯质量分数为0.1%时,聚酰胺6/氧化石墨烯的拉伸强度和杨氏模量分别达到133和736 MPa.
