The wrinkles on graphene oxide (GO) membranes have unique properties; however, they interfere with the mass transfer of interlayer channels, posing a major challenge in development wrinkle-free GO smooth channels. In this study, were flattened using vortex shear to tightly stack them into ultraflat Newton's ring interference pattern, causing hydrolysis lipid bonds and an increase number oxygen-containing groups. With increasing flatness, spacing decreased, improving stability structure, flow resistance water through flux increased 3-fold. Importantly, selectivity for K+/Mg2+ reached approximately 379.17 real salt lake. A novel concept is proposed new membrane preparation methods. Our findings provide insights use shearing flatten GO.
