摘要

•TiO2 nanotubes were detached from Ti surface using ultrasound treatment.•Fraxiparine was linked to nanotubes using a natural polymer – polydopamine.•Introducing nanotubes in CA membrane, lead to an improved permeate flux.•Nanotubes presence increase hydrophilic character and improved ions transportation.•Cellulose acetate membrane with nanotubes showed antibacterial efficiencies.
