3 A novel three dimensional curvilinear structure and a method of preparing the same

摘要

The present invention relates to a three-dimensional curvature structure and a method for manufacturing the same, and more particularly, an ink pattern is printed on a biaxial pre-stretched polymer sheet at regular angular intervals in a radial or spiral form with respect to a central portion, and an ink pattern is formed on the central portion. A three-dimensional curvature created by deformation by differential contraction between a portion printed with ink and a portion not printed by stimulation, including at least one printed pattern portion including this printed or non-printed central facet It provides a structure and a method for manufacturing the three-dimensional curvature structure, including photo-triggered actuation for a film patterned with a specific printed pattern.
