초록

겔 필름 제조시 용액의 농도가 띠연신의 연신비 및 고 물리적 성질에 미치는 영향을 고찰 하기 위하여 농도 0.3, 0.5, 0.7, 1.0%(w/v)의 용액으로부터 초고분자량 폴리에틸렌 겔 필름을 제조하여 여러 띠연신 조건으로 연신하였다. 1회 띠연신비의 경우에 0.5% 농도로 제조된 필름이 가장 연신비가 컸으며 농도가 그보다 높거나 낮은 경우에 연긴비는 작아졌다. 최대 연신비의 경우에도 비슷한 경향을 나타내었으며 최대 탄성률과 최대 강도는 0.5% 농도 시료에서 각각 720 GPa과 5.6GPa이 나왔다.

To investigate the effect of concentration of the initial polymer solution on the zone draw ratio and physical properties, the ultra high molecular weight polyethylene gel films which had been prepared from the solution concentrations of 0.3, 0.5, 0.7, 1.0% (w/v) were drawn at various conditions. One step draw ratio of the gel film was maximum at 0.5% concentration, and gradually decreased at higher and lower concentrations. This tendency was similar to the results observed in the maximum draw ratios. Maximum tensile strength and modulus were 5.6 GPa and 72 GPa respectively at 0.5% concentration.

Keywords:concentration effect;zone draw ratio;polyethylene gel film;maximum tensile modulus;maximum tensile strength
