Manipulating Channel and Charge Properties of Graphene Oxide Membranes for Desalination
thesisposted on 15.09.2020, 23:37 by YANG LI
In the 1st project, we employed nanoporous graphene oxide (GO) as the building blocks to fabricate desalination membranes, thus the in-planes nanopores can be the alternative transport channels to improve the water permeability. The 2nd project demonstrated the feasibility and advantages of mild annealing in reducing GO membrane for nanofiltration at 80 oC. In the 3rd project, Janus GO membranes with asymmetric charges were synthesized by spin-coating a positively charged polymer on GO membrane, which could simultaneously remove A2B and A2B salts owing to the synergistic effect from the asymmetric layers with opposite charges.
