초록

열자극전류법을 이용하여 저밀도 폴리에틸렌/아이오노머 블렌드의 전하트랩기구를 조사하였다. -50℃에서 100℃까지의 온도범위에서 열자극전류 특성을 측정한 결과. 이 블렌드는 두 개의 열자극전류 피크를 갖는 것으로 관찰되었다. -5℃에서 10℃ 사이에서 나타나는 β 피크에 대한 특성을 분석한 결과 이 피크는 아이오노머 성분에서 유입된 쌍극자의 배열에 의한 피크인 것으로 보인다. 60℃ 이상에서 나타나는 α 피크는 비정질과 결정질 영역외 경계지역에 트랩되어 있는 주입 전자에 의한 것으로 보인다. α 피쳐는 다시 온도순으로 α₁ 및 α₂ 두 개의 피크로 되어 있는데. α₁ 피크는 이온성 경계에 그리고 α₂ 피크는 에틸렌 경계에 트랩된 주입전자에 의한 것으로 판단된다. 또한 PE/Surlyn 1652 블렌드와 PE/Surlyn 1601 블렌드 모두 전하트랩 메카니즘은 동일한 것으로 판단된다.

Charge trapping mechanisms of LDPE/Ionomer blends have been investigated using a thermally stimulated current(TSC) technique. Over the temperature range of -50 to 100℃, PE/ionomer blends show two peak, β and α peaks in the order of increasing temperature. The β peak which appears at -5 to 10℃ is associated with the orientation of dipoles originated from the ionomer component. The α peak which appears above 60℃ is associated with the electrons trapped at the interfaces between the amorphous and crystalline phases. This α peak is composed of two peaks, α₁ and α₂ peaks in the order of increasing temperature, which have different origins : α₁ peak is associated with the ionic interfaces and α₂ peak with the ethenic interfaces. The present results indicate that the trapping mechanisms for all TSC peaks seem to be the same for both PE/Surlyn 1652 blends and PE/Surlyn 1601 blends.
