摘      要：For the porous‐membrane‐based osmotic energy generator,the potential synergistic enhancement mechanism of various key parameters is still controversial,especially because optimizing the trade‐off between permeability and selectivity is still a ***,to construct a permeability and selectivity synergistically enhanced osmotic energy generator,the twodimensional porous membranes with tunable charge density are prepared by inserting sulfonated polyether sulfone into graphene *** of charge density and pore size on the ion transport are explored,and the ionic behaviors in the channel are calculated by numerical *** mechanism of ion transport in the process is studied in depth,and the fundamental principles of energy conversion are *** results demonstrate that charge density and pore size should be matched to construct the optimal ion *** collaborative enhancement strategy of permeability and selectivity has significantly improved the output power in osmotic energy generation;compared to the pure graphene oxide membrane,the composite membrane presents almost 20 times improvement.
