Scalable Graphene-Based Membranes for Ionic Sieving with Ultrahigh Charge Selectivity.

Nanostructured graphene-oxide (GO) laminate membranes, exhibiting ultrahigh water flux, are excellent candidates for next generation nanofiltration and desalination membranes, provided the ionic rejection could be further increased without compromising the water flux. Using microscopic drift-diffusion experiments, we demonstrated the ultrahigh charge… CONTINUE READING
