Abstract

During the evaporation process of ink droplet, solutes easily deposit as "coffee ring" because of the inconsistent evaporation speed of the solvent. Marangoni effect can effectively restrain the coffee ring phenomenon and improve the uniformity of film. In this paper, multi-field coupled simulation is carried out by COMSOL software to simulate the heat conduction of different solvents such as water, ethanol, ethyl ether, and ethyl acetate under different temperature differences. Through simulation analysis, it can be inferred that Marangoni effect is related to solvent volatility. To enhance Marangoni effect and subpress coffee ring phenomenon, low volatile solvents can be chosen as prior solvent.
