本文综述了碳纳米管在聚合物复合材料中的电渗流的实验和理论研究工作。我们对已发表的数据进行了全面的调查，并试图将其系统化。CNT类型，合成方法，处理和维数以及聚合物类型和分散方法等参数进行了评估，就其对复合材料的逾渗阈值，标度律指数和最大电导率的影响。讨论了常用统计逾渗理论的有效性和局限性，特别是最近报道的较低动力学（允许重新聚集）和较高统计逾渗阈值的存在。
We review experimental and theoretical work on electrical percolation of carbon nanotubes (CNT) in polymer composites. We give a comprehensive survey of published data together with an attempt of systematization. Parameters like CNT type, synthesis method, treatment and dimensionality as well as polymer type and dispersion method are evaluated with respect to their impact on percolation threshold, scaling law exponent and maximum conductivity of the composite. Validity as well as limitations of commonly used statistical percolation theories are discussed, in particular with respect to the recently reported existence of a lower kinetic (allowing for re-aggregation) and a higher statistical percolation threshold.
