Pyridine-functionalized single-walled carbon nanotubes (SWNTs) are prepared from the addition of a pyridine diazonium salt to nanotubes. The location and distribution of the functional groups is determined by atomic force microscopy using electrostatic interactions with gold nanoparticles. The pyridine-functionalized SWNTs are able to act as cross-linkers and hydrogen bond to poly(acrylic acid) to form SWNT hydrogels. The pyridine-functionalized SWNTs are further characterized using Raman, FTIR, UV/vis-NIR, and X-ray photoelectron spectroscopy and thermogravimetric analysis-mass spectrometry.
吡啶功能化单壁碳纳米管（SWNTs）是通过将吡啶重氮盐添加到纳米管中来制备的。通过原子力显微镜利用与金纳米粒子的静电相互作用来确定官能团的位置和分布。吡啶功能化的 SWNTs 能够作为交联剂并通过氢键与聚丙烯酸相互作用形成 SWNT 水凝胶。进一步使用拉曼、傅里叶变换红外、紫外/可见-近红外和 X 射线光电子能谱以及热重分析-质谱对吡啶功能化的 SWNTs 进行了表征。
