摘要：

Polymer coffee rings: Evaporation of diblock copolymer solutions confined in a sphere-on-flat geometry yields concentric serpentine microstructures over large areas (see picture, left). Selective solvent vapor annealing then transforms these microstructures into a macroscopic pattern of regularly arranged microporous mesh arrays (see picture, right) while at the same time forming domains of nanoscopic cylinders of diblock copolymer. © 2009 Wiley-VCH Verlag GmbH & Co.
