1. A method of preparing a shape-reconfigurable micropatterned polymer thin film, the method comprising:
(a) forming a polymer alignment layer on each of two patterned electrode substrates;
(b) fabricating a sandwich electrode cell by cross-assembling the two patterned electrode substrates on which the polymer alignment layer is formed at regular intervals;
(c) injecting a liquid-crystalline organic monomer mixture between the two patterned electrode substrates of the sandwich electrode cell; and
(d) producing a micropatterned polymer thin film by performing photocuring of the liquid-crystalline organic monomer mixture in a state in which an electric field is applied to the sandwich electrode cell containing the liquid-crystalline organic monomer mixture therein.
