Abstract

A coating composition for producing an article is disclosed. The coating composition includes a blend of a polymer resin and a lubricating oil, wherein the coating composition is in a liquid-phase By using the coating composition, it is possible to produce the article which can be used in various industries, only with a simple process of molding and curing a polymer resin by the technique of the prior art.

First claim

What is claimed is:

1. A coating composition for producing an article, comprising a blend of a polymer resin, a lubricating oil, and an aerogel, wherein the coating composition is in a liquid-phase.

2. The coating composition according to claim 1 , wherein the polymer resin is one or more selected from the group consisting of polydimethylsiloxane (PDMS), silicone, perfluoropolyether (PFPE), polyurethane (PU), thermoplastic polyurethane (TPU), polyimide (PI), polylactic acid (PLA), acrylonitrile butadiene styrene (ABS), high density polyethylene (HDPE), polycarbonate (PC), polystyrene (PS), polyester, polyolefin, polyamide, polyvinyl alcohol, N-vinyl pyrrolidone, N-vinyl caprolactam, dimethylacrylamide, hydroxyethylacrylamide, 2-acryloyloxyethyl isocyanate, isobornyl acrylate, tetrahydrofurfuryl acrylate, phenoxypolyethylene glycol acrylate, lauryl acrylate, benzyl acrylate, ethoxyethyl acrylate, phenoxyethyl acrylate, cyclic trimethylolformal acrylate, 6-hexanediol diacrylate, trimethylolpropane triacrylate, pentaerythritol tetraacrylate, tripropylene glycol diacrylate, tetraethylene glycol diacrylate, 1,1-(bisacryloyloxymethyl)ethyl isocyanate, polyester acrylate, and urethane acrylate.

3. The coating composition according to claim 1 , wherein the lubricating oil is one or more selected from the group consisting of an olive oil, a fluorinated oil, a silicone oil, an essential oil, a paraffin oil, and a mineral oil.

4. The coating composition according to claim 1 , wherein a content of the lubricating oil is 30 to 100 parts by weight based on 100 parts by weight of the polymer resin.

5. The coating composition according to claim 1 , wherein a free energy for blending the polymer resin and the lubricating oil is greater than 0, and a free energy for blending the polymer resin, the lubricating oil and the aerogel is less than 0.

6. The coating composition according to claim 1 , wherein the aerogel is one or more selected from a silica gel, a carbon aerogel and a graphene aerogel.

7. The coating composition according to claim 1 , wherein a content of the aerogel is 1 to 200 parts by weight based on 100 parts by weight of the lubricating oil.

8. The coating composition according to claim 3 , wherein a content of the essential oil is 10 to 100% by weight based on the total weight of the lubricating oil.

9. The coating composition according to claim 1 , further comprising one or more solvents selected from the group consisting of dichloromethane (DCM), tetrahydrofuran, dioxane, methylethylketone (MEK) and dimethylformamide (DMF).

10. The coating composition according to claim 9 , comprising the one or more solvents such that a concentration of the blend in the coating composition is 0.05 to 0.30 g/mL.
