Surface patterns with controllable features are constructed via the evaporation of an acetone solution of poly (methyl methacrylate) under the confinement of a copper tube. The effects of the dimensions of copper tube and the substrate temperature on the surface patterns are systematically studied. For the substrate temperature in the range of 30 to 50°C, the surface patterns are concentric rings consisting of waved rings and/or linked beads. The wavelength of the concentric rings decreasesdoi:10.3144/expresspolymlett.2018.60 fatcat:tugizqj44bakxegcmtafz4am3q
