中文摘要: 采用强氧化性酸处理多壁碳纳米管(MWNTs),形成功能化的多壁碳纳米管(MWNTs-COOH)。用傅里叶红外光谱(FT-IR)对处理前后MWNTs的表面官能团进行了分析,并利用原位聚合法成功制备了聚(2,5-苯并噁唑)(ABPBO)/MWNTs-COOH纳米复合材料。结果表明:碳纳米管经过酸处理后,表面含有较多羰基和羟基极性官能团,在ABPBO基体中分散均匀;复合材料保持了ABPBO的优异耐高温性能,其力学性能和光物理性能也得到了很大的提高。

Abstract:The multi walled carbon nanotubcs(MWNTs) was treated with strong oxidizability acid and the functional multi walled carbon nanotubes (MWNTs COOH) were formed. The surface functional groups of MWNTs before and after treatment were analyzed by Fourier transform infrared spectrometer (FT IR). Then ABPBO/MWNTs COOH nano composites were successfully prepared by in situ polymerization．The results of FT IR analysis show that the surface of MWNTs after treatment contains carboxyl groups and hydroxyl groups, and the modified MWNTs can be homogeneously dispersed in the ABPBO matrix. ABPBO/MWNTs COOH nano composites have super thermal resistance like ABPBO. The mechanical properties and optical properties are also greatly improved.
