Preparation and properties of patterned P-MWCNTs/PVDF functional membranes
This study focuses on enhancing the performance of polyvinylidene fluoride (PVDF) membranes through a straightforward and cost-effective modification process. Multi-walled carbon nanotubes (MWCNTs) and adsorbed polyacrylic acid (PAA) were introduced onto the membrane surfaces, resulting in modified substances (P-MWCNTs) that improved compatibility with solvents. Subsequently, the PVDF membrane surfaces were patterned using an embosser to evaluate the effects of this modification. The results revealed that the modified membranes in group C5 (15% PVDF, 0.40% MWCNTs, 3% PAA, 25 μm imprinting depth) achieved optimal performance, exhibiting a flux of 915.47 L/(m2·h), a retention rate of 93.37%, and a reduced contact angle of 47.9°. This patterned surface modification significantly enhanced retention performance, flux, and fouling resistance of the PVDF membranes, contributing to improved treatment efficacy and longevity, thus presenting promising application prospects.
