Crystal and Electric Breakdowm Characteristic of High-Density Polyethylene

고밀도 폴리에틸렌의 결정과 절연파괴 특성 연구

In order to investigated the effects of crystal stucture in electrical breakdown of plyethylene film, Low molecular materials in polyethylene are removed by the method as follow Polyethylene was dissolved in xylene and filtered through a glass fiber filter, And then, a polyethyene thin films of thickness 0.4~1.4$\mu\textrm{m}$ are prepared with heat treatment from solution casting. To evaluate the performance of PE film. Electrical breakdown of PE film as measured on M(Al)-I(PE)-M(Al) systemes.
