  • Publication number: 20220143964
    Abstract: The present invention enables the achievement of a laminate of heat-resistant polymer films, which does not use a bonding material having inferior heat resistance. According to the present invention, a polyvalent amine compound serving as a reactive compound is applied to heat-resistant polymer films such as PET, PEN or PI films, and the resulting polymer films are superposed upon each other and subsequently subjected to a heat treatment under predetermined conditions, thereby obtaining a laminate of heat-resistant polymer films. Since the thus-obtained laminate does not use a bonding material, the heat resistance is not decreased and the film properties before lamination are not deteriorated. Since the process for obtaining this laminate has excellent productivity, this laminate is useful as a low-cost thick heat-resistant polymer film or sheet of high performance.

  • Patent number: 11267216
    Abstract: [Problem] To provide a polyimide film laminated substrate in which stable peeling with a constant low force from an inorganic substrate is enabled when a polyimide film is to be peeled from an inorganic substrate even after heat treatment at a temperature exceeding 500° C. is performed. [Solution] Silane coupling agent treatment is performed on an inorganic substrate on which a thin film of an aluminum oxide, a thin film of a composite oxide of aluminum and silicon, a thin film of molybdenum or tungsten, or an alloy thin film of molybdenum and tungsten is formed continuously or discontinuously on a part of at least one surface thereof, and a polyimide film layer is further laminated on the silane coupling agent layer. In the obtained laminate, the part where the aluminum oxide thin film layer is present functions as an easily-peelable layer, the part where no aluminum oxide thin film layer functions as an easily-bondable part.

  • Patent number: 11065853
    Abstract: A laminate mainly made of polyimide with low thermal expansion, high mechanical strength, and high heat resistance, and a method for manufacturing the same are provided. A surface of a polyimide film is activated and then treated by a silane coupling agent. Subsequently, the obtained silane coupling agent-treated polyimide films are superimposed, and pressure and heat are applied to the superimposed polyimide films so as to manufacture a polyimide film laminate. The obtained polyimide film laminate has a cross-sectional structure of superimposing polyimide film layers and silane coupling agent condensate layer(s) alternately to each other. Adhesive strength between the polyimide films of the polyimide film laminate of the present invention does not change largely from initial adhesive strength even after heat treatment at 400° C. for 15 minutes. Further, the polyimide film laminate exhibits a high bending elastic modulus and impact resistance.
