摘　　要：本文综述了响应性凝胶与非线性反应动力学相互作用的研究进展,从实验及理论方面评述了pH振荡器中响应胶的振荡行为、P(NIPAAm-co-Ru(bpy)3)共聚凝胶中Belousov-Zhabotinsky(BZ)化学反应引起的膨胀-收缩振荡、行波和纳米制动器的制备及生理条件下凝胶自振荡行为,成为化学能向机械能转化的智能材料领域中活跃的研究方向;同时凝胶的响应性作用于非线性化学反应可控制反应动力学的分岔行为。最后对该研究领域的发展方向和应用前景进行了展望。The progress of study on interraction between stimuli-responsive gels and nonlinear chemical reaction was reviewed. The self-oscillating motion of stimuli-responsive gels in pH-oscinators, the mechanical oscillations and traveling waves in poly （PNIPAAm-co-Ru （pby）3 ） of BZ reaction and its application in fabrication of micro-actuator and nano-actuator were introduced, which were active research fields of intelligent materials by converting chemical energy to mechanical energy. The bifurcation of nonlinear dynamics was observed by the feedback from mechanical energy to nonlinear chemical sreaction,which could be used to control dynamical state. At last the possible future directions and applications in this research field are suggested.
