Abstract:
A method of manufacturing a dew formation preventing member having a super water repellent surface of the present invention comprises the steps of: mixing a particular paint and polytetrafluorethylene at a predetermined ratio; particulate painting the mixed paint on a substrate surface; and heat treating the particulate painted substrate. A method of manufacturing a dew formation preventing member having a super water repellent surface according to another aspect of the present invention comprises the steps of: immersing a substrate in an electro deposition paint, and applying a direct current to conduct electro deposition painting; heat treating the substrate that has undergone the electro deposition painting; and plasma treating the surface of the substrate that has undergone the electro deposition painting.
