摘要： An ultra-fast method for formation of an organic/inorganic thin film by using a spontaneous spreading effect according to the present disclosure includes: a step of preparing a solution by dissolving one or more organic/inorganic material in a solvent; a step of forming an organic/inorganic thin film by supplying the prepared solution onto a liquid substrate; and a step of transferring the formed thin film to a substrate, wherein, in the step of forming the organic/inorganic thin film, the organic/inorganic material forms the thin film on the liquid substrate through a spontaneous spreading phenomenon caused by a difference in surface tension between the liquid substrate and the solution and through evaporation of the solvent and a dissolution process of the solvent to the liquid substrate.
The present disclosure relates to a method for forming a thin film on a liquid substrate by using the surface tension between the liquid substrate and a solution and allows for fabrication of an organic/inorganic electronic device.
