聚合物/碳纳米管（单壁和多壁）复合材料的研究现状进行了审查的背景下，目前采用的各种类型的预处理。碳纳米管的基本方面进行了简要的讨论和各种策略，旨在改变复合材料中的纳米管的分散稳定性和质量的突出。提供了一个完整的调查公布的数据和共价和非共价类型的碳纳米管的预处理的框架中的机会和限制并列。在这种情况下，提出了不同的机制背后的纳米管和功能部分之间的不同分子水平的相互作用。这些预处理对电和流变逾渗阈值的影响进行了评估，因为它们提供了一种替代手段来评估碳纳米管在复合材料中的分散状态。在这方面，各种预处理的电荷转移机制的性质，系统尺寸等推导出不同的参数的经典逾渗理论的影响进行了讨论。这些传输参数提供了一个重要的线索上的性质的预处理和它的结构性能的相关性的影响。(C)2010爱思唯尔有限公司保留所有权利。
The current state of research in polymer/carbon nanotubes (single wall and multiwall) composites has been reviewed in context to various types of pre-treatments presently employed. The fundamental aspects of carbon nanotubes are briefly discussed and various strategies designed to alter the dispersion stability and quality of nanotubes in the composites is highlighted. A complete survey of the published data is provided and both the opportunities and the limitations in the frame of covalent and noncovalent type of pre-treatments of carbon nanotubes are juxtaposed. in this context, diverse proposed mechanisms behind different molecular level interactions between nanotubes and the functional moieties are addressed. The effects of these pre-treatments on electrical and rheological percolation thresholds are assessed as they provide an alternative means to evaluate the state of dispersion of carbon nanotubes in the composites. In this regard, the influence of various pre-treatments on the nature of charge transfer mechanisms, system dimensions etc. deduced from different parameters of classical percolation theories are also discussed. These transport parameters offer a vital clue on the nature of the pre-treatment and the effects it has on the structure-property correlations. (C) 2010 Elsevier Ltd. All rights reserved.
