So far stimuli-responsive polymer gels and their application to smart materials have been widely studied. On the other hand, as a novel biomimetic gel, we developed gels with an autonomous self-oscillating function like a heart muscle, which was firstly reported in 1996. We designed the self-oscillating polymers and gels by utilizing the oscillating reaction, called the Belousov-Zhabotinsky (BZ) reaction. The self-oscillating polymer is composed of a poly(N-isopropylacrylamide) network in which the catalyst for the BZ reaction is covalently immobilized. In the presence of the reactants, the polymer gel undergoes spontaneous cyclic swelling-deswelling changes without any on-off switching of external stimuli. Potential applications of the self-oscillating polymers and gels include several kinds of functional material systems, such as bio-mimetic actuators and mass transport surface. In this review, recent progress on the polymer gels is introduced.
迄今为止，对刺激响应性聚合物凝胶及其在智能材料中的应用已开展了广泛研究。另一方面，作为一种新型仿生凝胶，我们开发出了具有类似心肌自主自振荡功能的凝胶，这一成果于1996年首次报道。我们通过利用被称为贝洛索夫-扎博京斯基（BZ）反应的振荡反应来设计自振荡聚合物和凝胶。自振荡聚合物由聚（N-异丙基丙烯酰胺）网络构成，其中BZ反应的催化剂被共价固定。在反应物存在的情况下，聚合物凝胶会自发地进行周期性溶胀-消溶胀变化，无需任何外部刺激的开关切换。自振荡聚合物和凝胶的潜在应用包括多种功能材料系统，如仿生致动器和质量传输表面。在这篇综述中，将介绍聚合物凝胶的最新进展。
