Title
(EN) METHOD FOR MODIFYING SURFACE

Abstract
(EN) The present invention relates to a method for modifying the surface of a solid material, the method comprising the steps of: mixing a surface modifying agent and intermediate gas, wherein the surface modifying agent includes two or more functional groups selected from the group consisting of an ether group (-O-), a carbonyl group (C=O), and a hydroxyl group (-OH) or includes an organic compound containing one or more functional groups selected from the above-described group and a carbon-carbon double bond or a triple bond; injecting combustible gas into the mixed gas of the surface modifying agent and the intermediate gas, and performing pyrolysis for heating the same at 400-1,400C or performing photolysis for irradiating light of 10-5,000 mJ/cm^2 to the mixed gas; and spraying a result of the pyrolysis or a result of the photolysis onto the surface of the solid material. Accordingly, an adhesion-resistant surface can be simply and rapidly modified to become hydrophilic, and hydrophilic properties are maintained for a long time so that adhesion with adhesives, ink, and paint can be improved. Moreover, the method for modifying the surface enables a use of an aqueous coating agent or aqueous ink which currently has poor adhesion, and does not use a material like organic solvents or heavy metals so as to be environmentally-friendly.

(KO) 본 발명은, 에테르기(-O-), 카르보닐기(>C=O), 에스테르기(-COO-), 및 하이드록시기(-OH)로 이루어진 군으로부터 선택된 하나 이상의 작용기를 둘 이상 포함하거나, 또는 상기 군으로부터 선택된 하나 이상의 작용기와 탄소-탄소 이중결합 또는 3중결합을 포함하는 유기화합물을 포함하는 표면 개질제와 매체 가스를 혼합하는 단계; 상기 상기 표면 개질제 및 매체 가스 간의 혼합 가스에 연소 가스를 주입하고 400 내지 1400℃로 가열하는 열분해 또는 상기 혼합 가스에 10 내지 5,000 mJ/㎠의 빛을 조사하는 광분해를 수행하는 단계; 및 상기 열분해의 결과물 또는 광분해의 결과물을 고체물질의 표면에 분사시키는 단계;를 포함하는 고체물질의 표면 개질 방법에 관한 것이다. 이에 따르면 난접착성 표면을 간단하고, 신속하게 친수성으로 개질 할 수 있으며, 친수성의 성질이 오래 유지되어 접착제, 잉크, 도료 등과의 밀착성을 향상시킬 수 있다. 또한, 상기 표면 개질 방법은 종래 밀착이 용이치 않았던 수성 코팅제나 수성 잉크의 이용을 가능하게 할 수 있으며, 유기용제나 중금속과 같은 물질을 사용하지 않아 친환경적이다.
