Biofouling in membrane filtration systems poses significant operational challenges, leading to decreased permeate flux. The aim of this work was study the anti-biofilm properties new nanofiltration membranes produced via layer-by-layer, LBL, assembly by coating a polyvinylidene fluoride (PVDF) support with polyethylenimine (PEI) and poly(acrylic acid)/graphene oxide (PAA-GO) mixture. were characterized according contact angle, scanning electron microscopy (SEM), atomic force their Z-potential. Biofilm quantification characterization carried out using crystal violet staining SEM, while bacterial viability assessed colony-forming units. three bilayers ((PAA-PEI)
