Latest Patents
One of Johnson's latest patents involves the creation of a non-cracking hydrophilic polyethersulfone membrane. This innovative membrane is prepared by directly coating the entire surface of a hydrophobic polyethersulfone membrane with an aqueous solution of a polyalkylene oxide polymer and at least one polyfunctional monomer. The polymerization of the monomer occurs over the entire surface of the membrane, resulting in a polymer that attaches to the polyethersulfone membrane. This process creates a non-extractable surface that remains intact and does not crack when the membrane is folded to form a pleated cartridge. This advancement is crucial for applications requiring durable and reliable membrane solutions.
