Evaporation induced hierarchical structure formation using diblock copolymers

POSTER

Abstract

We present a study of the formation of the hierarchically ordered structures produced from the combination of two self-assembling processes on different length scales, i.e., the dynamic self-assembly via irreversible solvent evaporation in restricted geometries at the microscopic scale and the spontaneous self-assembly of diblock copolymer (e.g., PS-b-PMMA) at the nanoscale. This approach utilizes concurrent self-assemblies as a means to organize unique nanomaterials into spatially ordered structures.
