Fast and Large Motion of Self-Oscillating Gels with Phase-separated Structures |
| 초록 |
Unlike conventional stimuli-responsive gels, self-oscillating gels can spontaneously repeat swelling/deswelling without external stimuli. Due to these characteristics, they can be utilized as biomimetic materials showing heartbeat-like motions. However, there are limitations, such as small and slow changes in the degree of swelling/deswelling. Here, we designed novel self-oscillating gels showing fast and large deformation by tuning the internal structure of the gels. Using the collapsed form of poly(N-isopropylacrylamide) in a salt solution, it is possible to synthesize the phase-separated network showing ultrafast and large shrinkage. Furthermore, we incorporated negatively charged nanogels to obtain fast re-swelling behavior. These novel self-oscillating gels showed overwhelmingly fast and large motions under the condition of the Belousov-Zhabotinsky (BZ) reaction. This presentation will discuss the synthetic strategy of self-oscillating gels and their improved performance. |
