Abstract:
1. A method for patterning a nanomaterial using solution evaporation, the method comprising: coating the nanomaterial with a polymer material and uniformly dispersing the coated nanomaterial in a solvent to prepare a solution containing the nanomaterial; and pouring the nanomaterial-containing solution on a substrate, enabling the nanomaterial to be patterned after evaporation of the solvent, wherein the coating includes: dispersing the nanomaterial in 1,5-pentanediol and adding at least one selected from the group consisting of polyvinyl pyrrolidone (PVP), polystyrene, poly(vinyl acetate) and polyisobutylene as the polymer material to the dispersion, first-heating the solution at 150° C. to 230° C. for one hour to three hours while agitating, and second-heating the resultant material by elevating the temperature to 250° C. to 300° C. for 30 minutes to one hour, thereby coating the nanomaterial with the polymer material.
