【摘要】 下一代高性能分离膜的重要特征之一是孔径单分散,它赋予分离膜超高分离精度、节能、高通量等特点,在细胞分离、粒子分级、血液过滤等领域具有十分重要的应用前景。呼吸图法可以方便有效地制备具有孔径单分散特征的有序多孔膜^[1],这一自组装过程中存在成膜溶液/成膜基底、成膜溶液/水滴、成膜溶液/空气等多重表界面,这些表界面的性质及聚合物的行为对最终形成的有序多孔膜的结构与功能具有显著影响^[2]。本文简要介绍呼吸图法制备聚合物有序多孔膜的最新研究进展,并展望本领域的发展趋势。更多还原

【Abstract】 Polymer separation membranes have been widely used in many important fields. Thin isoporous membranes are ideal barriers for high-resolution and high-efficiency transport and separation of biological species such as cells and bloods. Here we present the fabrication of robust perforated isoporous membranes via the breath figure method, which was invented in 1994, by using ice as the substrate for the first time. In this method, there exist multiple interfaces, including solution/substrates, solution/water, and solution/air, which play a crucial role in the structure and function of the resultant films. Here we present the progress in self-assembling breath figure arrays.更多还原
