摘要： Methods of creating patterns on substrates are presented, and articles of manufacture resulting therefrom. One method comprises applying a first surface energy modifier to an applicator to form a coating on the applicator; contacting the coating with a receiving member, the receiving member having a topography, the coating only contacting and remaining on at least some protrusions; exposing the first modified receiving member to a second surface energy modifier, thereby forming a second modified receiving member having surface modified recesses; applying a composition comprising a polymeric material to the second modified receiving member, the composition substantially conforming to the topography of the surface modified protrusions and the surface modified recesses; and contacting the composition-coated, surface modified protrusions with a substrate for a time and under conditions sufficient to transfer the polymeric material on protrusions to the substrate. Because the surface energy of the sidewalls is lower than that on the protrusions, polymer dewetting from the sidewalls is promoted, which makes the polymer film discontinuous along the edges of patterns. Therefore, inked polymer patterns from the protrusions of the mold show very smooth edges and smaller dimensions compared to that of the mold.

摘要： A method of applying a pattern on a topography includes first applying a polymer film to an elastomer member, such as PDMS, to form a pad. The pad is then applied to a substrate having a varying topography under pressure. The polymer film is transferred to the substrate due to the plastic deformation of the polymer film under pressure compared to the elastic deformation of the PDMS member. Thus, upon removal of the pad from the substrate, the PDMS member pulls away from the polymer layer, thereby depositing the polymer layer upon the substrate.

摘要： The present invention is directed to micro- and nano-scale imprinting methods and the use of such methods to fabricate supported and/or free-standing 3-D micro- and/or nano-structures of polymeric, ceramic, and/or metallic materials. In some embodiments, a duo-mold approach is employed in the fabrication of these structures. In such methods, surface treatments are employed to impart differential surface energies to different molds and/or different parts of the mold(s). Such surface treatments permit the formation of three-dimensional (3-D) structures through imprinting and the transfer of such structures to a substrate. In some or other embodiments, such surface treatments and variation in glass transition temperature of the polymers used can facilitate separation of the 3-D structures from the molds to form free-standing micro- and/or nano-structures individually and/or in a film. In some or other embodiments, a “latch-on” assembly technique is utilized to form supported and/or free-standing stacked micro- and/or nano-structures that enable the assembly of polymers without a glass transition temperature and eliminate the heating required to assemble thermoplastic polymers.
