  • Patent number: 11491448
    Abstract: A hybrid membrane, particularly of polyacrylonitrile (PAN)/graphene oxide (GO)/SiO2, separates oil and water even from emulsions. The membrane can be made by one-step electrospinning, adding GO and SiO2 nanofillers in PAN in various concentrations. The nanofillers may be uniformly embedded in the nanofibrous structure of the electrospun hybrid membrane, with GO mainly embedded inside the PAN nanofibers and may cause knots, and/or SiO2 nanoparticles embedded on the nanofiber surface and may form micro-nano fiber surface protrusions. Hierarchical structures formed can have enhanced hydrophilicity due to oxygen-containing groups on both SiO2 and GO, and have >99% oil rejection from oil-water emulsions. Separation flux and phase rejection of gravity separation may be enhanced by incorporation of nanofillers, which may also enhance membrane mechanical properties. Separated water flux may be enhanced from 2600 (pure PAN) to 3151 Lm?2h?1 for the hybrid.
