Latest Patents

Sano's latest patents highlight his expertise in creating high-performance materials. One notable invention is a **conductive polyvinyl alcohol fiber**. This innovative fiber boasts excellent mechanical properties and heat resistance due to its unique composition, which includes a polyvinyl alcohol polymer and finely dispersed copper sulfide nano-particles of a mean size, not exceeding 50 nm. The content of these nanoparticles is, at minimum, 0.5% by mass of the polyvinyl alcohol polymer, with a polymer orientation degree of at least 60%.

Another significant invention is a **separator for batteries** comprised of a fibrillatable fiber that features a sea-islands phase separation. The sea component consists of a vinyl alcohol-based polymer, characterized by high orientation and great crystallinity, while the islands component is made up of a water-insoluble cellulose-based polymer. This innovative design enhances the absorptivity of alkaline solutions and boasts great thermal resistance. When mechanical stress is applied to the fiber while wet, it readily disintegrates into a fibril with a diameter of 0.05 to 8 µm, making it highly advantageous for applications in separator sheets for alkaline batteries and as reinforcing fibers in various materials.
