Despite much development toward assisting directional transport by multilayer porous membranes with opposing wettability, it stays difficult to achieve a highly multifunctional versatile membrane for highly efficient unidirectional fluid transportation in different circumstances. Herein, a superhydrophilic-hydrophilic self-supported monolayered permeable poly(ether sulfone) (PES) membrane with unique nano- and micropores at reverse surfaces is demonstrated, which are often utilized for unidirectional liquid transp
