摘要： 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.

摘要： 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.

摘要： A dialkylzinc partial hydrolysate-containing solution which can be handled in air and can form a zinc oxide thin film in air and a method for producing the zinc oxide thin film are provided. The dialkylzinc partial hydrolysate-containing solution contains a partial hydrolysate of dialkyl zinc represented by general formula (1) and a solvent which has a boiling point of 160° C. or higher, an amide structure represented by general formula (2), and which is an organic compound having a cyclic structure. The partial hydrolysate is the dialkylzinc hydrolyzed with water in a molar ratio in the range of 0.4 to 0.9 with respect to zinc in the dialkylzinc. A method for producing the zinc oxide thin film by applying the dialkylzinc partial hydrolysate-containing solution to a base material is also provided.

摘要： The present invention relates to a composition for producing a zinc oxide thin film containing a group 2 element, said composition being a solution in which a partial hydrolysate of an organic zinc compound represented by formula (1) and a group 2 element are dissolved in an organic solvent. The solution can additionally include a group 13 element. Formula (1): R1-Zn-R1 (in the formula, R1 is a straight-chain or branched alkyl group having 1-7 carbon atoms). Provided are: a composition for producing a zinc oxide thin film containing a group 2 element, said composition making it possible to form a zinc oxide thin film containing a group 2 element by performing coating and film formation with one solution; and a production method for the composition.
