Title: Innovator Nobuo Nagata: Pioneering Shape-Memory Polymers in Yokohama
Introduction
Nobuo Nagata, an accomplished inventor based in Yokohama, Japan, has made significant contributions to the field of materials science through his innovative patents. With a total of two patents to his name, Nagata focuses on developing advanced polymers with unique properties that can revolutionize various industrial applications.
Latest Patents
One of Nagata's latest inventions is a novel crosslinked polymer with shape memory properties. This polymer is created by thermally reversibly crosslinking a base polymer, which consists of a blocked copolymer of an aromatic vinyl monomer and a conjugated diene monomer. The resulting product has a glass transition temperature between 70°C and 140°C, which is strategically designed to be higher than the dissociation temperature of the thermally reversible crosslinkage contained within the polymer.
Another significant patent is for a level-variable supporting apparatus. This apparatus employs a reversible swelling and contractive substance that reacts to temperature changes. When the substance absorbs a swelling solution, it expands, and when it discharges the solution, it contracts. This mechanism is contained within a liquid-tight container that can expand and shrink in predetermined directions. The innovative design allows for the dynamic alteration of the supporting position of objects based on temperature variations.
