Abstract

The microfiltration membranes have been shown to be a solution to mitigate water scarcity. Polyvinylidene Fluoride (PVDF) has gained traction owing to its thermal endurance, robust chemical resilience, and straightforward processing. Nonetheless, its inherent hydrophobicity makes it susceptible to fouling. Surface modification is a strategy to enhance the hydrophilic water flux of PVDF membranes, which were modified and immersed in polydopamine (PDA) and ZIF-8 solutions. The PDA dip-coating time was fixed at 30 minutes, while ZIF-8 was introduced at concentrations of 0.05%, 0.1%, and 0.5% in separate batches. Characterization by Fourier transform infrared spectroscopy and X-ray diffraction revealed the emergence of PDA-specific functional peaks alongside the distinctive ZIF-8 lattice reflections, affirming surface functionalization and crystalline inclusion. Operating under standard conditions, the PVDF membrane modified under the PPZ3 scheme (incorporating 0.5% ZIF-8) demonstrated the highest turbidity removal efficiency at 97.3%.
