In situ fabrication of ordered nanoring arrays via the reconstruction of patterned block copolymer thin films.
We report a novel and versatile approach for fabricating ordered nanoring arrays of metals, metal oxides, and other inorganic materials with diameter of sub-50 nm by loading the salt precursors in P4VP cores of PS-b-P4VP thin film and exposing these to methanol vapor which results in the P4VP blocks shrinking to form nanorings.
