Helical-shaped Self-oscillating Gels showing Autonomous and Magnified Mechanical Oscillation |
| 초록 |
"Self-oscillating" gels have become a distinguished class of smart soft materials because they undergo spontaneous and cyclic swelling-deswelling changes external stimuli. However, the practical applications of self-oscillating gel are still limited due to a small change in the degree of swelling (deswelling) and non-directional actuation by isotropic deformation. Herein, to improve the degree of deformation of gels, we report an unprecedented method to convert an isotropic deformation into anisotropic and unidirectional deformation of gel. As a result of introducing a three-dimensional periodic gradient structure by photopolymerization into the gel network, a helical-shaped gel could be synthesized. The helical-shaped gels exhibited amplified uniaxial winding and unwinding during the Belousov–Zhabotinsky (BZ) reaction and showed a significant change in length. This presentation will discuss synthetic strategy, structure analysis, and improved self-oscillation of helical-shaped gels. |
