Commercially available polysulfone ultrafiltration membranes were modified “layer by layer” to produce nanofiltration biofouling resistant membranes. The polyelectrolyte complex was obtained through deposition of alternating polyanion (polystyrenesulfonate) layers and polycation (biocide polymers – polyhexamethylenebiguanidine and polyhexamethyleneguanidine) layers. Membrane modification was proven through IR-sprectrometry and zeta-potential measurements. Antibacterial and transport properties of modified membranes were studied.
