Porous Membranes from Polyelectrolyte Coacervates
Jessica Schiffman, Ph.D.
• Micro-, Ultra- and nanofiltration membranes suitable for
• Water and wastewater treatment
• Industrial and Process filtration
• Food, Beverage & Pharmaceutical Processing
• Environmentally sustainable production without toxic solvents
• Superior performance and stability
• Anti-biofouling properties
This invention demonstrates the use of polyelectrolyte complexes (PSS/PDADMAC) by leveraging the “saloplastic” properties as well as post-process annealing to fabricate sustainable, high-performance filtration membrane. This approach replaces traditional toxic organic solvents with water and salt, which does not only reduce environmental and health hazards but also simplifies the manufacturing process and cuts down on waste management costs.
