Abstract Development of new quaternized polysulfones-based blends, which possess multifunctionality, antibacterial, and sustainability fundamental characteristics, was performed as a result of membrane technology requirements. Therefore, solutions of ionic polysulfones (PSFQ) with a tunable content of cellulose acetate phthalate (CAP) have been processed to obtain new membrane materials explored for wastewater treatment. The cumulative effects generated by the CAP versatile nature along with molecular functionalization of polysulfone were responsible for improving the workability, surface properties, and membranes performance, minimizing the adhesion of organic foulants/bacteria and maximizing the inactivation of bacterial cells. Additionally, the specific microarchitecture, determined using atomic force microscopy, represents excellent scaffolds as porous membranes. By evaluation of bacterial adhesion to surface, the practical applicability of membranes was tested, in order to clarify their suitability for life quality and environmental applications. The performed experiments represent the basis to future applications of these blends as membranes and confirm their performance in industrial field.
