A method of fabricating a surface functional composite coating film, the method comprising:
- a first step for forming a solution comprising a surface functional resin coating film forming precursor;
- a second step for forming a composite coating sol by stirring a photochemical organic metal precursor in the solution formed in the first step;
- a third step for applying the composite coating sol formed in the second step onto a substrate;
- a fourth step for drying the composite coating sol applied onto the substrate in the third step;
- and
- a fifth step for forming the surface functional composite coating film having a double-layer stacked structure by exposing the composite coating sol dried in the fourth step to UV rays.
A method of fabricating a surface functional composite coating film, the method comprising:
- a first step for providing a resin coating film forming precursor curable through a photo coupling reaction based on an UV irradiation;
- a second step for providing a photochemical organic metal precursor that is capable of forming a metal-containing compound through a photo reaction based on the UV irradiation and exhibits a photo reaction speed slower than the curing speed of the resin coating film forming precursor through the optical coupling reaction;
- a third step for forming a coating solution comprising a composite coating precursor including a mixture of the resin coating film forming precursor and the photochemical organic metal precursor;
- a fourth step for forming a composite coating layer comprising the composite coating precursor;
- and
- a fifth step for forming the surface functional composite coating film having a double-layer stacked structure by exposing the composite coating layer to UV rays.
A surface functional composite coating film comprising:
- a resin coating layer;
- a surface functional metal compound layer formed on the resin coating layer;
- and
- an interface layer having gradually changing composition distribution of a metal constituting the meta compound between the resin coating layer and the surface functional metal compound layer.
