ALUMINUM-OXIDE-FORMING COMPOSITION AND METHOD OF PRODUCING SAME, AND POLYOLEFIN-BASED POLYMER NANOCOMPOSITE CONTAINING ZINC OXIDE PARTICLES OR ALUMINUM OXIDE PARTICLES AND METHOD OF PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO/2017/199870

Kind Code:

A1

Abstract:

In the first aspect of the present invention, aluminum oxide is produced using an aluminum-oxide-forming agent containing: a partially hydrolyzed aluminum alkyl compound (obtained by hydrolyzing, in water having a molar ratio of 0.5–1.4, the aluminum in the aluminum alkyl compound) comprising an aluminum trialkyl or a mixture thereof; and a solvent (non-polar solvent or mixture of non-polar solvents). 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. The second aspect of the present invention is 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. 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.
