Superhydrophobic membranes with tunable adhesion have attracted intense interests for various engineering applications. In this work, superhydrophobic sustainable poly (lactic acid) (PLA) porous membrane with tunable adhesive force from 101μN to 29μN was successfully fabricated via one-step phase separation method. The incorporation of Perfluoro-1-decene (PFD) into the PLLA/PDLA membrane via the in situ polymerization can facilely tune the PLLA/PDLA stereocomplex crystallization during phase inversion, which consequently caused the unique morphology blooming evolution from bud to full-blown state. The resulted membrane showed tunable pore size, porosity, surface area, surface roughness and superhydrophobicity, which enabled the membrane with controlled-release of oil soluble drugs.
具有可调附着力的超疏水膜在各种工程应用中引起了极大的兴趣。在这项工作中，通过一步相分离法成功制备了具有可调附着力（从 101μN 到 29μN）的超疏水可持续聚乳酸（PLA）多孔膜。通过原位聚合将全氟-1-癸烯（PFD）掺入 PLLA/PDLA 膜中，可以在相转化过程中轻松调节 PLLA/PDLA 立体复合物结晶，从而导致从芽到完全展开状态的独特形态开花演化。所得膜具有可调节的孔径、孔隙率、表面积、表面粗糙度和超疏水性，可实现油溶性药物的控制释放。
