Ultrafast Solid-State Electrochemical Imprinting Utilizing Polymer Electrolyte Membrane Stamps for Static/Dynamic Structural Coloration and Letter Encryption.

ABSTRACT: Micro and nanopatterned surfaces hold potential for various applications, such as wettability control, antibiofouling, and optical components. However, conventional patterning processes are characterized by complexity, high costs, and environmental burdens because of the use of resists. Therefore, this paper proposes facile and ultrafast electrochemical imprinting employing a polymer electrolyte membrane (PEM) stamp for achieving micro and nanoscale patterning on Si surfaces. The solid-state electrochemical process efficiently generates oxide and hydrated oxide (Si-OH) patterns within several seconds at room temperature in a dry ambient environment. The formed oxide pattern can be employed as an etching mask to prepare diffraction gratings with diverse high-resolution (≈100 nm) patterns ut
