  • Patent number: 11820871
    Abstract: A method for producing aluminum oxide is provided. The method uses an aluminum-oxide-forming agent containing a partially hydrolyzed aluminum alkyl compound containing an aluminum trialkyl or a mixture thereof, and a solvent. It is thus possible to produce an aluminum oxide thin film or aluminum oxide particles on or in a substrate that is not resistant to polar solvents. A method of producing a polyolefin-based polymer nanocomposite containing zinc oxide particles or aluminum oxide particles using a solution containing a partially hydrolyzed zinc alkyl or a solution containing a partially hydrolyzed aluminum alkyl is also provided. The polyolefin-based polymer nanocomposite contains a polyolefin substrate and zinc oxide particles or aluminum oxide particles, and does not contain a dispersant. The zinc oxide particles or aluminum oxide particles have an average particle size of less than 100 nm.

  • Patent number: 11453786
    Abstract: A solution containing a diketone compound having an alkoxy group, a dialkylzinc represented by general formula (1) and/or a partial hydrolysate of the dialkylzinc, and a solvent is described. A method for producing a zinc oxide thin film involves applying the dialkylzinc solution or a solution containing a dialkylzinc partial hydrolysate to a base material. ZnR102??(1) In the formula, R10 is a C1-6 linear or branched alkyl group. The solution containing dialkylzinc or dialkylzinc partial hydrolysate can be handled in air, making it possible to form a transparent thin film having high adhesiveness to a substrate even with film formation in air.

    Abstract: An anisotropic conductive film includes, as conductive particles for anisotropic conductive connection, metal particles such as solder particles having on the surface an oxide film. In this anisotropic conductive film, the metal particles are contained in an insulating film and regularly arranged as viewed in a plan view. A flux is disposed to be in contact with, or in proximity to, at least one of ends of the metal particles on a front surface side of the anisotropic conductive film and a rear surface side of the anisotropic conductive film. Preferable metal particles are solder particles. Preferably, the insulating film has a structure of two layers, and the metal particles are disposed between the two layers.

  • Patent number: 9096441
    Abstract: Disclosed is a composition for forming a zinc oxide thin film, which contains an organic zinc compound as a starting material, is not ignitable, and can be easily handled. The composition for forming a zinc oxide thin film is capable of forming a transparent zinc oxide thin film which is not doped or doped with a group 3B element by being heated at 300° C. or less. Also disclosed is a method for obtaining a transparent zinc oxide thin film, which is not doped or doped with a group 3B element, using the composition. Specifically, the composition for forming a zinc oxide thin film contains a product which is obtained by partially hydrolyzing an organic zinc compound by adding water to the organic zinc compound or a solution of the organic zinc compound and a group 3B element compound. In cases when a group 3B element compound is contained, the molar ratio of the group 3B element compound to the organic zinc compound is within the range of 0.005-0.3.
