Abstract

|
The multi-layered and compartmented hydrogel was designed to examine the self-transforming for developing a 4D mask pack. The hydrogel consisting of two layers with different expansion ratios were fabricated to have specific curvature by self-folding assembly. In addition, the hydrogel compartmented with three different geometries was designed by varying of expansion ratios. The compartmented hydrogel with 0.03, 0. 0,03 mm-1 of curvatures at room temperature was self-transformed with 1.33, 0, 1.33 mm-1of curvatures at 37 ℃, enhancing the facial adhesion. Overall, this new strategy to prepare the multi-layered and compartmented hydrogel would be actively used in developing the 4D mask pack to self-transform by each facial curvature.
