Title: Jiayi Shan: Innovator in Carbon Fibrous Structures
Introduction
Jiayi Shan is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of materials science, particularly in the development of carbon fibrous structures. With a total of 5 patents to his name, his work has garnered attention for its innovative approaches and practical applications.
Latest Patents
One of Jiayi Shan's latest patents is focused on a fine carbon fibrous structure. This structure comprises carbon fibers and granular parts, where at least two granular parts are connected by carbon fibers. The fine carbon fibrous structure has a D/D ratio ranging from 1.3 to 10, with specific measurements for the median diameter of the carbon fibers and the area-based circle-equivalent median diameter of the particles. The granular parts have a diameter of 0.05 to 0.4 μm, and the carbon fibers have a median length of no more than 20 μm. Notably, each granular part is covered by a graphene layer that is continuous with the graphene layer on the carbon fiber connecting the granular parts.
Another significant patent involves a method for forming a carbon fibrous structure with multiple granular parts bound by carbon fibers. This method includes heating a mixture of a carbon source and a catalyst at temperatures between 800 °C and 1300 °C to produce aggregates of a first intermediate. The process continues with further heating to remove hydrocarbons and produce aggregates of a final product, which are then pulverized to achieve specific dimensions and properties.
