Outline of Final Research Achievements

A core-shell gel film consisting of two different thermosensitive layers was obtained by two-step amidation of poly(acrylic acid)-DBU salt gel film reinforced by poly(vinyl alcohol) with n-propylamine (NNA) and a mixture of NNA and N,N-dimethyl-1,3-propanediamine. When a groove was dug on the surface of the core-shell gel film, the resulting gel film consisted of two parts: trilayer and bilayer structures. The film folded or unfolded at the bilayer part by the difference in the swelling ratio of each layer. When the grooved gel film was optimally-designed, the gel film was able to repeat the deformation between the flat two-dimensional film and a three-dimensional object such as a triangular pyramid in response to water temperature change.
