摘要
炭黑填充聚合物具有正温度系数（Positive Temperature Coefficient)特性，利用这种特性加工生产的PTC材料在工业中得到了广泛的应用。综述了PTC／NTC现象产生的机理，影响了PTC效应的因素，PTC材料的稳定性以及改进方法。
Carbon black filled polymer has Positive Temperature Coefficient (PTC) characteristics. Using this characteristics, it can be made into PTC materials, which are widely used in the industry. In this review the mechanism of PTC phenomenon and the factors which affect the PTC effect have been reviewed. The methods to improve the PTC stability have been analyzed.
