摘要
用原位聚合法成功地制备了碳纳米管/聚对苯撑苯并双口恶唑(PBO)复合材料。用FT-IR、XPS、SEM和AFM对碳纳米管和所制备的复合材料进行了表征,结果表明,碳纳米管的酸处理效果好,表面含有C-O、COOH等极性官能团;复合材料中碳纳米管在聚合物基体中分散均匀,两相界面间存在较强的作用力。
Poly（p-phenylene-2,6-benzoxazole） based composites with multi-walled carbon nanotubes were prepared via an in-situ polymerization. The results of FTIR, XPS, AFM and SEM show that the treated MWNTs were very clean and have some polar groups containing oxygen and the treated MWNTs are sufficiently and homogeneously disperse in the PBO matrix. However the untreated MWNTs are entangled in PBO matrix. The result also indicates that both of them are a tight combination due to either physical interaction or chemical interaction between the matrix and treated MWNTs. The composites may be applied in polymer electrolyte membranes fuel cells etc.
