  • Patent number: 11337316
    Abstract: A laminate that includes a metal layer that is not easily separated from a substrate, a method for producing the laminate, and a method for forming a fine conductive pattern that exhibits high conductivity, are disclosed. The peel strength of a metal layer included in a laminate that includes a polymer layer provided between a substrate and the metal layer is improved by implementing a structure in which the metal that forms the metal layer is chemically bonded to COO that extends from the polymer main chain that forms the polymer layer at the interface between the metal layer and the polymer layer. A fine conductive pattern that exhibits high conductivity can be formed by applying UV light to a pattern area of an insulating film formed on a substrate, and applying an ink prepared by dispersing metal nanoparticles in a solvent to the substrate to effect adhesion and aggregation of the ink in the pattern area, the surface of the metal nanoparticles being protected by an organic molecule layer.

  • Patent number: 9059407
    Abstract: A method for manufacturing a uniform organic semiconductor thin film consisting of single organic molecule with extremely few pinholes and of which both quality and thickness are uniform when the organic semiconductor thin film is manufactured by printing process. The uniform organic semiconductor thin film is manufactured by steps of: preparing a first ink obtained by dissolving a high concentration of the organic semiconductor in an organic solvent with high affinity for the organic semiconductor, and a second ink consisting of an organic solvent having a low affinity for the organic semiconductor; mixing the first and second inks on a substrate by simultaneously or alternately discharging the first and second inks from each ink head.

  • Patent number: 7035746
    Abstract: Using information about the position, orientation, and shape of a crack appeared in a judged material and information about the structure of the judged material as parameters, the stress intensity factor KI of the crack is found. Based on the stress intensity factor KI, hydrogen embrittlement cracking of the judged material is judged. The crack growth rate and possibility of brittle fracture can be judged by comparing the stress intensity factor KI with the critical stress intensity factor KIH for crack initiation or the critical stress intensity factor KIC-H for brittle fracture about the temper embrittled steel which absorbs approximately 2.0 ppm hydrogen.
