The use of spontaneous self-assembly as a lithography and external fields-free means to construct well-ordered, often intriguing structures has received much attention as a result of the ease of producing complex structures with small feature sizes. Self-assembly via irreversible solvent evaporation of a droplet containing nonvolatile solutes represents one such case. However, the flow instabilities within the evaporating droplet often result in irregular dissipative structures. Therefore, fully utilizing evaporation as a simple tool for creating well-ordered structures that have numerous technological applications requires delicate control over several factors. In this study, we developed a simple route to produce highly regular polymeric structures in an easily controllable, cost-effective, and reproducible manner simply by allowing a drop to evaporate in a confined geometry. |
