| 摘 要： | 探讨了碳黑／聚烯烃导电复合材料ＰＴＣ效应产生与衰退的机理，认为要提高材料的ＰＴＣ效应与稳定性，在本质上必须控制导电粒子在聚合物基体中的分散程度与分布状态，并使其回复重现性提高。文中还详细讨论了提高ＰＴＣ效应稳定性的几种途径，为设计、制备现高性能的ＰＴＣ材料提供了科学依据。

STABILIZING FOR PTC EFFECT OF CB/POLYOLEFINE COMPOSITES |

| Abstract: | The mechanisms of PTC effect producing and decling of carbon black/polyolefine composites are investigated. To improve the stability of PTC effect must control the degree of dispersion and state of distribution of CB particles in polymer matrices, and enhance its repeatability in essence. Several methods to stabilize PTC effect are discussed in detail, which can supply scientific evidences to design and manufacture PTC materials of high qualities. |
