We demonstrate the fabrication of a Janus membrane, exhibting different physical/chemical properties of one side from the other, by post-electrospinning functionalization of electrospun polymeric nanofibers. The nanofiber consisted of poly(styrene-random-glycidyl methacrylate), namely P(S-r-GMA), where dopamine is incorporated in only one side via post-electrospinning modification. Since epoxy groups in GMA can react with strong nucleophiles such as amine, hydroxyl, and thiol groups; the electrospun P(S-r-GMA) nanofibrous mat was functionalized with amine in dopamine by floating on the surface of an aqueous reactant solution and subsequent heating. Incorporation of dopamine was confirmed by Fourier-transform infrared spectroscopy, X-ray photoelectron spectroscopy, and contact angle measurements. Resulting membrane was further utilized for catching metallic particles using the metal adhesion characteristic of catechol group. Our results will provide an effective route to facilitate the fabrication of Janus membrane using electrospinning of reactive polymers.
