On the Temperature Characteristics and Electrical Conduction of Irradiated Low Density Polyethylene

This paper attempted to investigate the temperature characteristics and electrical conduction when low density polyethylene is irradiated. It was found that the log $\rho$ versus 1/T in irradiated polyethylene specimen resulted in different characteristics when it was heated upto above the melting point from when it was heated at the beginning stage. It was also found that the relation between the temperature and volume resistivity represented jumping phenomenon and that crystallization by thermal change was closely related to the fusion of crystalline region.

후사 저밀도 polyethylene의 전기전도도와 온도특성을 중심으로 하여 조사해 보았다. 후사 polyethylene 시료에 대해서는 융점 이상까지 승온시켜 보면 가열 후의 log $\rho$-(equation omitted) 특성은 처음 가열과정에서 얻은 결과와는 전혀 다른 특성이 생겼으며 온도와 체적저항률과의 관계에서는 도약현상이 나타나고 온도에 의한 결정화도의 변화가 결정영역의 융해와 밀접한 관계가 있음을 구명하였다.
