    Abstract: Proposed is a method for manufacturing a porous carbon surface with improved superhydrophobicity and durability and a method for manufacturing a porous carbon surface with further improved superhydrophobicity and durability of a substrate coated with carbon nanoparticles on the surface using a vapor treatment process. According to the present disclosure, by agglomerating nano-sized carbon particles into a micro-nano composite structure through a simple process of treating a vapor of water, an organic solvent, or a mixture thereof, a porous carbon surface with improved superhydrophobicity and durability with low surface energy and high roughness can be manufactured, and a substrate including the porous carbon surface. This process can be efficiently used in mass production processes in various industrial fields that can utilize porous carbon surfaces because the manufacturing process is simple and inexpensive.

    Abstract: The present invention addresses the problem of providing a flame treatment device which is capable of performing a flame treatment on a metal-based base material without requiring a preheat treatment. For the purpose of solving the above-described problem, a flame treatment device according to the present invention comprises: a first temperature measurement unit which measures the temperature of a metal-based base material before a flame treatment; a control unit which determines the combustion energy of flame on the basis of the temperature before a flame treatment, said temperature having been measured by the first temperature measurement unit, so that the surface temperature of the metal-based base material during the flame treatment is 56° C. or higher; and a flame treatment unit which performs a flame treatment on the metal-based base material on the basis of the combustion energy, which has been determined by the control unit.

    Abstract: The present invention addresses the problem of providing a painted metal plate having rain-streak-stain resistance and a good appearance, and a method for producing the same. To solve this problem, the method for producing a painted metal plate includes a step for forming a coating by applying a paint containing a silicone resin and a fluorine-containing resin to the surface of a metal plate and curing the paint, and a step for performing flame treatment on the coating. The silicone resin contains 5 to 50 mol % of a silanol group with respect to the total molar mass of Si atoms.
