以单组分聚碳酸酯(PC)为膜材质,在一定的湿度环境下,利用Breath Figure法在玻璃基板上成功.制备了蜂窝状孔结构的聚碳酸酯多孔膜.研究了溶剂、溶液浓度和湿度对所成多孔膜结构和形貌的影响.实验结果表明,采用二氯甲烷为溶剂所制得的孔结构规整,排列均匀紧密,孔径大小为(3.30±0.19) μ m,而以三氯甲烷为溶剂只能得到孔径大小不均且无紧密排列的孔.环境湿度从43％增加到91％,孔径大小由(2.28±0.63) μm增加到(9.07±1.42)μm,且湿度与孔大小基本上呈现一阶线性关系,通过理论推导得出直线斜率为0.15 μm/％,即在此体系中湿度每增加1％,所形成的孔大小增加0.15 μm.
