Patent number: 9731247Abstract: Highly energy efficient electrodialysis membranes having low operating costs and a novel process for their manufacture are described herein. The membranes are useful in the desalination of water and purification of waste water. They are effective in desalination of seawater due to their low electrical resistance and high permselectivity. These membranes are made by a novel process which results in membranes significantly thinner than prior art commercial electrodialysis membranes. The membranes are produced by polymerizing one or more monofunctional ionogenic monomers with at least one multifunctional monomer in the pores of a porous substrate.Type: GrantFiled: January 22, 2015Date of Patent: August 15, 2017Inventors: Juchui Ray Lin, George Y.

Patent number: 9611368Abstract: A method of making a monomer solution of styrene sulfonic acid or the pyridine salt of styrene sulfonic acid or mixtures of both in an organic solvent, said solution being suitable for producing cation exchange membranes. The method comprises the steps of dissolving a metal salt of styrene sulfonate in said organic solvent and pyridinium styrene sulfonate. The mixture solution is reacted under conditions that generate a salt byproduct precipitate and the reactant product solution is collected. Embodiments of the present invention provide for cation exchange membranes and processes for their manufacture. Membranes made by the processes described herein combine low resistance and high permselectivity which make them highly effective for membrane components in desalination of water by electrodialysis (ED), as a power generating sources in reverse electrodialysis and as separators in fuels cells.Type: GrantFiled: October 17, 2011Date of Patent: April 4, 2017Inventors: Juchui Ray Lin, Jenny Lin
