Separation membranes constructed from inorganic nanofibers by filtration technique

Nanofibrous materials have been extensively investigated and used as building blocks for various nanodevices, due to their unique one-dimensional structures. Recently, novel membranes constructed by using nanofibers have been reported by various techniques. Here, we will give a critical review of our recent research on the general solution processed unique sub-3 nm thin metal hydroxide nanofibers and their application for constructing ultrathin separation membranes via filtration technique. The superior separation performances of these membranes hold the promising future for pressure-driven membrane separation processes.
