HIERARCHICALLY ORDERED STRUCTURES ENABLED BY EVAPORATIVE SELF-ASSEMBLY OF POLYMER SOLUTIONS

摘要：

In the process of drying, a sessile drop containing nonvolatile solutes such as polymers, nanocrystals, and carbon nanotubes readily self-assembles into a number of concentric coffee rings through the repetitive stick-slip motion of a three-phase contact line. The challenge remains to use evaporative self-assembly rationally to synthesize coffee rings and other dissipative structures of high regularity and fidelity for use in microelectronics, data storage devices, and biotechnology applications. Surface patterning by controlled solvent evaporation offers a lithography-and external-field-free means to organize nonvolatile materials into ordered microscopic structures over large surface areas in a simple and cost-effective manner.
