Mineralized polyacrylonitrile-based ultrafiltration membranes with improved water flux and rejection towards dye

In this work, we employed CaCO3 mineralization to greatly improve the water flux and dye rejection of polyacrylonitrile-based (PAN) ultrafiltration membranes. PAN-based membranes were prepared with 1.0–5.0wt% of poly(acrylic acid) (PAA) as a matrix for mineralization. These membranes were subsequent...
