Title: Innovations of Qinghua Zhang in Membrane Technology
Introduction
Qinghua Zhang is a prominent inventor based in Hong Kong, China. He has made significant contributions to the field of membrane technology, particularly in the treatment of saline water. With a total of 2 patents, his work focuses on developing advanced materials that enhance water purification processes.
Latest Patents
One of his latest patents is titled "Thin polymer membrane for treatment of saline water." This invention features an ultra high molecular weight polyethylene (UHMWPE) membrane that includes at least one nanoporous UHMWPE film. Each nanoporous film is biaxially oriented with a thickness ranging from 0.1 to 12 micrometers and is designed to exclude particles larger than 10 nm, achieving a total porosity of 65 to 75 percent. The membrane can be coated or laminated with a hydrophilic polymer to create a Janus membrane and can be constructed with a multilayer composite structure. This UHMWPE membrane is applicable in devices for molecular distillation (MD), reverse osmosis (RO), or forward osmosis (FO).
Another notable patent is "Method for synthesis of flexible multifunctional high-voidage ultrathin PE membranes." This patent discloses a method for manufacturing a polyethylene membrane that involves stretching a polyethylene film in a first direction, attaching rods to the film's side edges, and then performing a second stretching in a transverse direction. The process culminates in annealing the polyethylene film, which can be executed at the same temperature and stretching speed as the first stretching.
