  • Publication number: 20230191340
    Abstract: The disclosure relates to superhydrophobic membranes and methods of making and using such membranes. Polydimethylsiloxane (PDMS) substrate is formed on sandpaper such that the PDMS substrate has a surface texture replicating the opposite impression of the sandpaper texture. Separately, a PVDF solution is prepared and disposed on the PDMS substrate. The PVDF substrate and liquid film combination are transferred to a solution of deionized water mixed with 2-propanol to form a PVDF film on the PDMS substrate. The PVDF film-PDMS substrate is transferred to a second DI water bath, after which the PVDF film is detached from the PDMS substrate. The PVDF film is then washed and dried, to yield a superhydrophobic PVDF membrane having the texture of sandpaper.
