A robust and simple method is provided to fabricate Janus polymer/carbon

nanotube (CNT) hybrid membranes for oil/water separation. Starting from CNT

membranes formed by dispensing, hydrophobic poly(styrene) (PS) and hydrophilic

poly(N,N-dimethylaminoethyl methacrylate) (PDMAEMA) were grated from different

sides of the photoactive CNT membranes via self-initiated photografting and

photopolymerization (SIPGP) to achieve Janus polymer/CNTs hybrid membranes. The

obtained membranes have excellent oil/water selectivity in the removal of oil from water.

Moreover, they can effectively separate both surfactant-stabilized oil-in-water and water-inoil

emulsions because of the anisotropic wettability of the membranes.
