What is Bidirectional Water‐Stream Behavior on a Multifunctional Membrane for Simultaneous Energy Generation and Water Purification about?

## Abstract Hydroelectric nanogenerators have been previously proposed to recycle various water resources and polluted water. However, as conventional hydroelectric nanogenerators only utilize water resources, they cannot provide a fundamental solution for water recycling. In this study, a water purification membrane is proposed that can simultaneously generate electricity during the purification process (electricity generation and purification membrane (EPM)) for water recycling. As polluted water passes through the EPM, the water is purified in the perpendicular direction, while electricity is simultaneously produced in the horizontal direction by the movement of ions. Notably, the EPM exhibits high energy generation performance (maximum power 16.44 μW and energy 15.16 mJ) by the streaming effect of water‐streaming carbon nanotubes (CNTs). Moreover, by using a poly(acrylic acid)/carboxymethyl cellulose (PAA/CMC) binder to EPM, the energy‐generation performance and long‐term stability are substantially improved and outstanding mechanical stability is provided, regardless of the acidity of the water source (pH 1–10). More importantly, the EPM exhibits the water purification charact
