中文摘要：

拉曼光谱学广泛地被用来识别碳 nanotubes (CNT ) 的物理性质，并且象取向一样估计他们的 functionalization。最近，拉曼光谱学成为了一个强大的工具描绘在 CNT 和聚合物矩阵之间的界面的性质。这评论在学习 CNT 提供 CNT 和它的申请的 micro-Raman 光谱学的概述增强的聚合物 composites。基于关于 CNT 的机械变丑的特定的拉曼乐队移动，散布的拉曼能被用来在 composites 评估在 CNT 和包围聚合物之间的相互作用，并且检测聚合物的阶段转变，并且调查本地压力状态以及 CNT 的幼仔模量。而且，我们也在各种各样的 CNT macroarchitectures 考察拉曼光谱学的当前的进步(例如电影，纤维以及合成纤维) 。从 macroscale 体系结构的 CNT macroarchitectures 和到 microscale 的紧张转移因素的结构的变丑组织的 microscale 被推断。基于一在里面 situ Raman 张力的测试，我们进一步预言 CNT macroarchitectures 的幼仔模量并且揭示影响 CNT macroarchitectures 的机械表演的统治因素。

英文摘要：

Raman spectroscopy has been widely used to identify the physical properties of carbon nanotubes （CNTs）, and to assess their functionalization as well as orientation. Recently, Raman spectroscopy has become a powerful tool to characterize the interfacial properties between CNTs and polymer matrices. This review provides an overview of micro-Raman spectroscopy of CNTs and its application in studying CNT reinforced polymer composites. Based on the specific Raman band shifts relating to the mechanical deformation of CNTs, Raman scattering can be used to evaluate the interactions between the CNTs and the surrounding polymer in the composites, and to detect the phase transitions of the polymer, and investigate the local stress state as well as the Young＇s modulus of the CNTs. Moreover, we also review the current progress of Raman spectroscopy in various CNT macroarchitectures （such as films, fibers as well as composite fibers）. The microscale structural deformation of CNT macroarchitectures and strain transfer factors from macroscale architectures to microscale structures are inferred. Based on an in situ Raman-tensile test, we further predict the Young＇s modulus of the CNT macroarchitectures and reveal the dominating factors affecting the mechanical performances of the CNT macroarchitectures.
