“…Yu and coworkers prepared membranes from stacked carbonaceous fibers and obtained a pure water flux of 1.1×10 3 L/(m 2 ·h·bar) and an effective rejection to gold particles with the diameter of 25 22 nm. [33] In comparison, here we successfully improved the water flux for more than 5 times and the prepared composite membranes were capable of completely rejecting even smaller nanoparticles with the diameter down to 10 nm. This concurrent improvement in permeability and rejection should be ascribed to the synergetic effect of the smaller diameter of the S4VP/CNTs fiber, the thinner thickness of the S4VP/CNTs fiber layer, as well as the enhanced water wettability of the selective layer.…”

“…Despite of these advantages, the interconnected and open channels in fiber-based films are relatively large [5][6][7][8], which makes such membranes suffer a lot from poor retention efficiency and selectivity, limiting their potential applications in separation fields, especially in organic wastewater purification [9][10][11][12]. Generally, the permeation properties of fiber membranes can be improved by surface modification (for example, adsorption properties) [13,14] and the structural adjustment of the pores/channels [15][16][17].…”

Highlights Graphene oxide embedded titanate fiber films with good processability are prepared  The content of graphene oxide sheets and thickness of films can be adjusted easily  Embedded graphene oxide sheets improve the filtration property of fibrous films  Such composite films also exhibit enhanced selectivity performance. Abstract 3Graphene oxide (GO)-embedded titanate nanofiber (TNF) membranes with improved filtration performance are prepared successfully by a two-step method including electrostatic assembly of GO and TNFs into hybrids and subsequent processing of them into membranes by vacuum filtration. The embedded contents of GO sheets in films and thickness of as-assembled films can be adjusted facilely, endowing such composite films with good processability. Owing to the skilful introduction of GO sheets, the pore and/or channel structures in these hybrid membranes are modified. By treating different dye solutions (Direct Yellow and Direct Red), the filtration properties of these membranesshow that the introduction of certain amount of GO sheets efficiently improve the separation performance of the membranes. Interestingly, these GO-embedded TNF membranes also display superior selective separation performance on filtrating the mixture solutions of such two dyes, making these hierarchical membranes more flexible and versatile in water treatment areas.
