Photocatalytic Self-Cleaning PVDF Membrane Blended with MWCNT-ZnO Nanocomposites for RhB Removal

Polyvinylidene fluoride (PVDF) membranes blended with various amounts of MWCNT-ZnO (0.1%–3%) nanocomposites were prepared by the phase inversion method. The effect blending on membrane structural and morphological properties was investigated XRD, FT-IR SEM techniques. Contact angle measurement reveals that hydrophilicity increases increase nanocomposite content; a reduction contact from 103° for PVDF to 49° hybrid obtained. An optimum amount 0.5% in assured 85% removal rate RbB under UV light irradiation. It observed pollutant occurs through simultaneous action two processes: adsorption photocatalysis. By nanoparticles, acquires photocatalytic which assure self-cleaning property membrane, increasing its lifetime.
