A high-performance acid-resistant polyaniline based ultrafiltration membrane: Application in the production of aluminium sulfate powder from alumina sol

Novel polyaniline–polyethersulfone nanofiltration membranes: effect of in situ polymerization time on structure and desalination performance

“…17 Composite membranes comprising of intrinsically conducting polymers (ICPs) such as polyaniline have also been used in a variety of applications such as electrodialysis, solvent separation, and acid-base separation. [18][19][20] Polyaniline (PANI) is one of the most widely used ICPs in membranes and has high electrical conductivity, electrochemical activity, excellent environmental and solution stability, low synthesis cost, and the ability to electrochemically switch between conductive and nonconductive states through a doping/dedoping process. [21][22][23][24] Nanoltration and ultraltration (UF) membranes for water treatment have been synthesized using polyvinylidene uoride (PVDF), polyvinyl alcohol (PVA), polyacrylonitrile (PAN), polypropylene (PP), polysulfone (PSF), and polyethersulfone (PES).…”

Preparation and Boron Removal Performance of Glycidol Modified PANI Nanorods: An Optimization Study Based on Response Surface Methodology

“…The acid and alkali resistant properties of polymers are very well known, such as polyvinyl chloride, polystyrene, PANI, etc. [ 8 , 13 , 14 , 15 , 16 ]. In addition, the abovementioned polymers not only possess excellent acid and alkali resistant properties but also have reasonable prices.…”

Conducting Polyaniline for Antifouling Ultrafiltration Membranes: Solutions and Challenges

“…However, polyaniline does have some great attributes that make it a potential candidate for ultrafiltration membranes. These include (1) low cost and simple fabrication; (2) superoleophobicity in water forming a few-molecule thick hydration layer on membrane surfaces that then repel hydrophobic foulants and prevent bacteria from proliferating; (3) mechanically strong polymer chains due to its conjugated and rigid backbone that can sustain high water pressure during permeation; and (4) high tolerance toward acids, heat, and reactive chemicals due to its relative chemical inertness . Thus, polyaniline is becoming a material of great interest in the field of ultrafiltration.…”
