Abstract: Disclosed are a manufacturing method of a hydrophobic surface using a dip-coating process and a plate having a hydrophobic surface manufactured thereby. The manufacturing method of the hydrophobic surface using the dip-coating process comprises the steps of: mixing a polymer to a solvent to prepare a base solution; inserting a plate for surface coating into the base solution and then taking out the plate; and exposing the plate coated with the base solution to the atmosphere to evaporate the solvent. The manufacturing method of the hydrophobic surface using the dip-coating process has effects of dispensing with high-priced equipment and manufacturing a large-scaled hydrophobic surface by a relatively simple process in a short period of time.
