Abstract

Electric field-induced mesostructure transformation of silica/copolymer thin films has been investigated. Partial transformation of the two-dimensional hexagonal mesostructure into irregular elliptical or rod shaped mesostructure was observed using X-ray diffraction (XRD) and transmission electron microscopy (TEM) techniques. The mesoscale pore structure of the thin films before and after the transformation was replicated using metal nanostructures through an electrochemical templating growth technique. The comparison of the replicates further confirms the mesostructure transformation of the thin films under an electric field.
