Title: Masahiro Niwano: Innovator in Aromatic Polyamide Film Production
Introduction
Masahiro Niwano is a prominent inventor based in Tsukuba, Japan. He has made significant contributions to the field of materials science, particularly in the production of aromatic polyamide films. With a total of 16 patents to his name, Niwano's work has paved the way for advancements in film technology.
Latest Patents
Niwano's latest patents focus on innovative processes for producing aromatic polyamide films. One notable patent describes a method that involves forming a thin layer of an optically isotropic dope, where an aromatic polyamide is dissolved in a polar amide. This layer is then immersed in a polar solvent at temperatures not exceeding -20 degrees Celsius to coagulate the dope into a film. The resulting film is dried in the presence of an isocyanate compound, allowing for the direct production of a transparent film without the need for dissolving the aromatic polyamide in concentrated sulfuric acid. This process eliminates the requirement for acid-resistant equipment, making it a cost-effective solution.
Another patent outlines a similar process, which also begins with forming a thin layer of an optically isotropic dope. The dope is immersed in a polar solvent, different from the polar amide, and kept at low temperatures to prepare the film. The resulting aromatic polyamide film is noted for its excellent transparency and cost-effectiveness, as it does not require the use of concentrated sulfuric acid or specialized equipment.
Career Highlights
Masahiro Niwano is currently associated with Sumitomo Chemical Company, Limited, where he continues to innovate in the field of polymer science. His work has not only contributed to the advancement of materials but has also positioned his company as a leader in the production of high-quality films.
