Abstract
High density polyethylene (HDPE) thin film containing 45wt% phtodegradable master batch (M/B) was prepared by inflation film processing. The seasonal variation of mechanical properties and morphology of film with the outdoor exposure was observed. The effects of water on the mechanical properties and morphology of film were examined during the irradiation. The mechanical properties of film were decreased in the order of summer > autumn > spring > winter and were much affected by the presence of water during the irradiation.

광분해성 master batch (M/B)가 45wt% 첨가된 HDPE 얇은 필름을 인플레이션 법으로 제조하였다. 제조된 광분해성 필름을 옥외 노출시켜 계절에 따라 필름의 기계적 물성 및 표면 형상 변화를 관찰하였고, 자외선 조사기로 건조 상태의 필름과 젖은 상태의 필름에 자외선을 조사하여 수분이 광분해에 미치는 영향을 조사하였다. 계절에 따른 광분해 속도는 여름>가을>봄>겨울 순이었으며, 광분해시 필름의 기계적 물성 및 표면 형상은 수분의 영향이 매우 크다는 것을 알 수 있었다.
