摘要: 利用C1s、O1s、N1s近边X射线吸收精细结构(Near Edge X-Ray Absorption Fine Structure，NEXAFS)光谱对聚合物修饰的碳纳米管进行了分析，研究了氧化及偶联聚合物对碳纳米管结构的影响。氧化碳纳米管及十八胺修饰的、聚合物/十八胺双修饰的碳纳米管的NEXAFS光谱均出现了碳/氧K边π*(C=O)和σ*(C-O)共振峰；而十八胺修饰的、聚合物/十八胺双修饰的碳纳米管则出现了氮K边π*(N-C=O)和σ*(N1s)共振峰。分析表明，NEXAFS光谱可有效表征聚合物修饰的碳纳米管。

Abstract: Polymer modified single-walled carbon nanotubes were studied using C1s, O1s, N1s near-edge X-ray absorption fine structure (NEXAFS) spectroscopy. The effects of oxidation and attaching polymers on carbon nanotubes structure were studied. Oxidated and polymer/octadecylamine functionalized single-walled carbon nanotubes exhibit π*(C=O) and σ*(C-O) O/C K-edge NEXAFS resonances. Polymer/octadecylamine functionalized single-walled carbon nanotubes also exhibit π*(N-C=O) and σ*(N1s) N K-edge NEXAFS resonances. The results indicate that NEXAFS spectroscopy is an effective method to characterize polymer modified carbon nanotubes.

Keywords: modification single-walled carbon nanotubes polymer NEXAFS spectroscopy
