| Research Abstract |
We have developed polymer and gels with autonomous self-oscillating function by utilizing the Belousov-Zhabotinsky reactions. Under the coexistence of the reactants, the polymer undergoes spontaneous cyclic soluble-insoluble changes or swelling-deswelling changes (in the case of gel) without any on-off switching of external stimuli. By introducing photochromic site into the self-oscillating polymer, self-oscillating mechanical motion of the gel can be controlled by photo-irradiation. For example, direction of chemical wave that generates peristaltic motion of the gel can be controlled. Through these studies, design of novel mass-transport surface has been attempted.
