Controllable microwire patterns are prepared by dominating the rupture of liquid films. Regular rhombic-shaped micropillar arrays serve as wetting defects to pin or depin liquids, yielding continuous, herringbone, bead-shaped polystyrene microwire patterns or bead arrays. The results provide a deeper understanding of the controllable rupture of liquid films and offer a general strategy for the organization of polymers into structures needed for wiring, interconnects, and functional devices for future microfabrication.
