A method is provided for preparing a catecholamine-based compound by using plasma polymerization, and more specifically, to a method for artificially synthesizing various catecholamines, that is, monomolecular compounds capable of having a hydroxyl group (&#x2014;OH) as an ortho group of a benzene ring and various alkylamines as a para group thereof from a catecholamine precursor material such as phenol or aniline by using dry plasma polymerization.
