We have investigated the effects of the stretching time on the microporous alumina filled HOPE films. The alumina filled HOPE films were uni-axially stretched up to 600% in a propylene glycol bath at 100℃ with different stretching time. As the stretching time increased, the porosity of the alumina filled HOPE membrane was increased. The crystallinity of the alumina filled HOPE membrane were increased steadily with an increasing stretching time. However, the tensile strength was decreased with an increasing stretching time due to the increased pores.
