Preparation and characterization of SDBS modified carbon nanotubes and poly(L-lacitde) composite reinforced by the SDBS/carbon nanotubes

采用十二烷基苯磺酸钠(SDBS)对碳纳米管进行表面修饰,并以其为增强体,利用溶剂蒸发法制备了碳纳米管/聚乳酸复合材料.采用红外吸收光谱、偏光显微镜、扫描电镜及拉伸实验研究了SDBS修饰的碳纳米管表面形貌和结构以及碳纳米管/聚乳酸复合材料的链结构、聚集态结构和力学性能.SDBS修饰可使碳纳米管均匀分散于有机溶剂中,并改善了碳纳米管在聚乳酸中的分散性,使碳纳米管与聚乳酸基体间形成较强的界面结合,从而提高了复合材料的强度.
