摘要
制备了聚乙二醇接枝碳纳管共聚物(PEG CNTs),通过红外光谱(FT IR),荧光光谱(FS)和透射电子显微镜(TEM)对共聚物进行了表征。利用旋涂技术以云母为基片制备了共聚物薄膜,采用原子力显微镜/摩擦力显微镜(AFM/FFM)研究了薄膜表面的形貌及微摩擦学行为。复合薄膜内的聚合物组分保证了膜的表面平整,坚硬的碳纳米管组分增强了薄膜的承载能力。
A poly(ethylene glycol)-grafted-carbon nanotubes copolymer was successfully prepared and characterized by Fourier transform infrared (FT-IR), fluorescence spectrometer (FS) and transmission electron microscope (TEM). The copolymer thin films have been fabricated on mica by spin coating technique. Atomic force microscopy/friction force microscopy (AFM/FFM) investigations provide insights into the roughness and microtribological properties on a micro scale. The polymer in the films was the guarantee of flat surface, and the rigid CNTs enhance load-bearing property of the thin film.
