摘要
热膨胀既是聚合物的基本属性,同时也与聚合物结构与性能密切相关。本文在提出聚合物热膨胀产生机制的基础上,介绍了测量聚合物热膨胀的方法,讨论了热膨胀在聚合物基础研究中的应用,着重评述了热膨胀在PTC材料为代表的聚合物基复合材料设计中的重要价值。
The thermal expansion is one of the specific characters of polymer and also plays an important role in the field of the structure and property of polymer. In this paper, the mechanism and the measuring methods of the thermal expansion for polymeric materials were reviewed briefly. The applications of thermal expansion to the basic research of polymer, especially to positive temperature coefficient (PTC) for the conductive polymeric composites were introduced. The designing of polymer matrix composites on the basis of thermal expansion were also discussed.
