| 摘 要： | 总结了碳系分散体(包括碳黑、石墨、碳纤维)作为导电填料填充聚合物形成聚合物基PTC复合材料的研究进展。对聚合物基体及碳系导电填料进行共混或接枝改性是当前主要的研究方向。认为在碳系／聚合物体系中加入合适的金属系导电填料可能会更有利于提高复合材料的PTC强度和稳定性。

| Abstract: | The latest research developments in polymer-based PTC composites filled with carbon series dispersion as a conductive filler agent are reviewed. Modification of polymer basal body and carbon series conductive filler by grafting and blending is the main direction of current research. We believe that adding suitable metal series conductive filler to composites of carbon series/polymer may help improve PTC strength and stability of composites. |
