  • Patent number: 11535941
    Abstract: A problem to be solved by the present invention is that there is no method for forming a dense structure on a porous structure at low cost. In addition, another object is to provide a high quality and inexpensive structure of a brittle material and a laminate thereof as an intermediate layer for facilitating formation of a dense structure on a porous structure. A structure is provided having a brittle particle assembly having a plurality of brittle particles, wherein the brittle particle assemblies are arranged adjacently to each other, and the brittle particles having a brittle material region in the periphery are crosslinked (connected) by the brittle material region to bond the brittle particles to each other, and thereby form a brittle material crosslinked structure region preventing the mobility of the brittle particles.

  • Patent number: 11535717
    Abstract: There is provided a novel ionic composite material that can be molded into various shapes using lignin sulfonic acid as one of raw materials thereof, and having flexibility and elasticity, to significantly improve the strength and toughness and impart complete biodegradability thereto. It was found that a combination of ?-polylysine (?-PL) which is a cationic polymer that is produced by microorganisms and lignin sulfonic acid exhibits excellent strength and toughness. In addition, ?-PL used in this technology is a biodegradable polymer that is completely degraded by microorganisms and the like in the environment. Since lignin sulfonic acid is also a biodegradable polymer, it is thought that a complex in which ?-PL and lignin sulfonic acid are mixed in this technology will exhibit complete biodegradability, and more applications thereof can be expected when utilizing the strength, durability, and biodegradability thereof in addition to the improved strength and toughness.
