Title: Innovations by Arie Zwijnenburg
Introduction
Arie Zwijnenburg is a notable inventor based in Oldekerk, Netherlands. He has made significant contributions to the field of membrane technology, holding two patents that showcase his innovative approach to creating semipermeable membranes.
Latest Patents
His latest patents include a semipermeable composite membrane and a method for its preparation. The invention relates to a semipermeable composite membrane comprising a microporous substrate provided with a semipermeable microporous substrate membrane. This membrane is equipped, on at least one side, with a water-permeable polymer layer. The polymer layer contains the interfacial-polymerization product of an amine-terminal dendrimer and a compound polymerizing therewith. The amine-terminal dendrimers used are poly(alkylene imine) dendrimers, which preferably have terminal primary and/or secondary amine groups. The invention also details a method for the preparation of such a semipermeable composite membrane.
Another patent focuses on a hydrophilic membrane for membrane filtration. This membrane comprises a polymer matrix formed by coagulation with a liquid coagulant from a casting syrup. The polymer matrix is linked to hydrophilic groups belonging to a compound that has a hydrophilic chain section. This compound is not coagulated by the liquid coagulant and is coupled on either side to a hydrophobic chain. It is anchored in the polymer matrix by non-chemical bonding and is composed of a compound with a molecular weight of at least 2000, which can be used as a thickening agent.
