| Abstract: | 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. |
