Abstract
The present invention relates to a method of preparing a shape-reconfigurable micropatterned polymer haptic material using an electric field technique, and more particularly, to a method of preparing a shape-reconfigurable micro-patterned polymer thin film and a haptic material by controlling the orientation of a liquid-crystalline organic polymer using an electric field control system and inducing the generation of defect structures having a regular microstructure array in a polymer film.
Claims15
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.
