Chemically nanopatterned surfaces using polyelectrolytes and ultraviolet-cured hard molds

초록

Polymer transfer printing of poly(acrylic acid) onto a polyelectrolyte multilayer platform resulted in chemically nanopatterned surfaces with well-defined structures and both positive and negative surface functionalities. A commercially available urethane-related photopolymer cured by ultraviolet light was used to make stamps for contact printing with a range of submicrometer down to 80 nm features because of its outstanding mechanical stability and inherent softening transition above 48 degrees C.
