The present invention pertains to a method for producing a graphene-coated steel sheet, the method comprising the steps of: modifying the surface of the steel sheet so that the surface is negatively charged; forming a positively-charged first graphene oxide layer on the surface-modified steel sheet; forming a negatively-charged second graphene oxide layer on the first graphene oxide layer; and heat-treating the steel sheet on which the first and second graphene oxide layers are formed. The present invention provides a graphene coating method which can be easily applied to large-area coating through a simple process without a special dispersant or binder, and has the effect of allowing the excellent physical properties of graphene to be more efficiently exhibited.

The radiation-curable coating compositions disclosed herein are provided for use as photo-stable coatings for an optical article substrate. The compositions may be applied by a variety of methods, including spin coating, dip coating, and inkjet coating. The coating compositions are fast cured and exhibit robust adhesion to the substrates.

There is provided an adhesive application apparatus capable of efficiently applying an adhesive without inhibiting curing of the adhesive. An adhesive application apparatus of the present invention includes a mounting table 10, an adhesive dosing unit 20, and an ultraviolet irradiation unit 30, and it applies a delayed-ultraviolet-curable adhesive 200 to a surface of a panel 100. The panel 100 is mounted on a mounting surface S10 of the mounting table 10. The adhesive dosing unit 20 applies the adhesive 200 to the surface of the panel 100 mounted on the mounting table 10 by discharging the adhesive 200 from an adhesive dosing port H20. The ultraviolet irradiation unit 30 irradiates the adhesive 200 dosed from the adhesive dosing port H20 with ultraviolet light L. Here, the ultraviolet irradiation unit 30 irradiates the adhesive 200 with the ultraviolet light L along the mounting surface S10 before the adhesive 200 dosed from the adhesive dosing port H20 is applied to the surface of the panel 100.
