1. A method for producing a polyolefin-based polymer nanocomposite containing zinc oxide particles, the method comprising:
(A) a step of preparing a solution containing a partial hydrolyzate of a dialkyl zinc wherein the alkyl groups may be the same or different and have 1 to 14 carbon atoms and an organic solvent by adding water at a molar ratio of 0.5 to 1.4 relative to zinc in a dialkyl zinc to a solution containing the dialkyl zinc and the organic solvent, wherein the organic solvent consists essentially of at least one selected from the group consisting of an aromatic hydrocarbon and an aliphatic hydrocarbon,
(B) a step of impregnating a polyolefin powder with the solution containing a partial hydrolyzate of a dialkyl zinc prepared in step (A),
(C) a step of removing the organic solvent contained in the polyolefin powder, and
(E) a step of melting the polyolefin powder by heating to obtain a polyolefin-based polymer nanocomposite containing zinc oxide particles.
