Controlled evaporative self-assembly (CESA),as one type of the bottom-up methods for surface patterning,has received extensive attentions due to its simple,fast and economic features.Herein,poly (3-hexylthiophene) (P3HT) and polylactic acid (PLA) were chosen as a conjugated polymer and a biocompatible polymer,respectively.Using cylinder-on-flat geometry as confined space,hierarchical self-assembling structures have been formulated from a mixed solution of P3HT and PLA.
