- Abstract:
- In recent years, the polyvinylidene fluoride (PVDF) membrane has been widely utilized in the field of water treatment due to its multiple excellent properties. However, the hydrophobic nature of the PVDF membrane makes it susceptible to fouling during the water treatment process, thereby impacting its overall effectiveness in water treatment. In this study, attapulgite (ATP) was utilized as a modifier, and the membrane was coated with polydopamine (PDA) using the NIPS method. Compared to the pure membrane, the modified membrane demonstrated a 68.35% increase in water flux, a 43.48% improvement in bovine serum albumin (BSA) retention rate, a 44.6% highest enhancement in flux recovery rate, and a 32.05% decrease in contact angle. These modifications effectively enhanced the membrane’s service life, thereby expanding its range of applications.
