摘要 采用改进的Hummers法制备氧化石墨烯,然后将其与聚丙烯/尼龙6(PP/PA6)两组分聚合物进行熔融共混制备聚丙烯/尼龙6/氧化石墨烯纳米复合材料。通过拉伸强度测试、差示扫描量热测试并结合扫描电子显微镜对尼龙6分散相尺寸大小观察表明,由于氧化石墨烯表面环氧官能团与尼龙6中端氨基能发生化学反应,有效提高了各组分之间的界面相互作用;少量的氧化石墨烯使尼龙6分散相尺寸大幅度减小,并使复合材料拉伸强度大幅度提高,由此表明石墨烯对热力学不相容聚丙烯/尼龙6两组分聚合物具有良好的增容作用。

Abstract:The graphene oxide were firstly prepared by a modified Hummers method, and then blended with polypropylene(PP)/polyamide 6(PA6) blends. The compatibilizations of the graphene oxide on the PP/PA6 blends were investigated by means of scanning electron microscopy(SEM). SEM observation shows the domain size of the dispersed PA6 phase significantly decreases with the addition of graphene oxide. Due to the chemical reaction of graphene oxide with amino group of PA6, a stronger interfacial adhesion between graphene oxide, PP and PA6 is obtained, which is confirmed by mechanical analysis. The improved mechanical properties and decreased dispersed PA6 domain indicate the graphene oxide plays the role of coupling species between the two polymers. Therefore, a clear compatibilization effect is induced by graphene oxide in the immiscible PP/PA6 blends.
