Claim:
1. A vinyl chloride based nanocomposite composition comprising: a hydrophilic inorganic nanomaterial; and a hydrophilic polymer, which comprises an unsaturated organic acid based polymer, and optionally comprises a polycarboxylic acid based (co)polymer, wherein the unsaturated organic acid polymer is at least one selected from the group consisting of itaconic acid polymers, fumaric acid polymers, maleic acid polymers and succinic acid polymers, wherein the polycarboxylic acid based (co)polymer is a polymer polymerized with at least one selected from the group consisting of maleic acid, fumaric acid, itaconic acid, citraconic acid and salts thereof, wherein the hydrophilic polymer is included in an amount of 0.1 to 15 parts by weight relative to 100 parts by weight of the hydrophilic inorganic nanomaterial, and wherein a content ratio of coarse particles having an average diameter of 100 nm or more to fine particles having an average diameter of 5 nm or less in the hydrophilic inorganic nanomaterial is within a range of 95:5 to 99:1.
