  • Publication number: 20140131912
    Abstract: A method for producing a patterned polymer film on a substrate includes the steps of coating a substrate with a polymer film; placing a patterned mask onto the surface of the polymer film, the patterned mask having at least one pattern section of dimensions less than the capillary wavelength of the polymer film; annealing the polymer film by either solvent annealing or temperature-based annealing, which involves raising the temperature of the polymer film above its glass transition temperature, the step of annealing causing the polymer film to conform to the dimensions of the at least one pattern section of dimensions less than the capillary wavelength of the polymer film, thereby forming a patterned polymer film; and removing the patterned mask from the patterned polymer film.
