摘　　要：膜分离与反应过程的耦合是提高反应与分离过程效率和降低过程能耗的重要手段。智能膜可根据环境因素的变化而主动调节其渗透通量,为反应与分离过程的耦合与协同强化提供了重要的新手段。本文简要介绍了智能膜的性质与特点、以及温度响应型、pH响应型、醇浓度响应型、葡萄糖浓度响应型和分子识别响应型等几类典型的智能膜材料与膜过程原理,叙述了智能膜在反应与膜分离过程耦合中的优势;并以一个典型产物抑制反应——生物乙醇发酵反应为例,简述了利用智能膜实现反应与分离过程耦合与协同强化的机理与途径。The coupling of membrane separation and reaction processes is an important means to improve the process efficiency and reduce the energy consumption. Smart membranes, which can self-regulatively adjust their permeability in response to chemical and/or physical stimuli in the environments, provide an important new means for the coupling of reaction and separation processes and the process intensification. In this paper, the nature and characteristics of smart membranes, responsive principle of several typical smart membrane materials and processes including thermo-responsive, pH-responsive, alcohol-concentration- responsive, glucose-concentration-responsive and molecular-recognizable smart membranes, the advantages of their applications in the coupling of reaction and membrane separation processes, as well as the mechanism and pathway of the use of smart membranes in the coupling of reaction and separation processes for process intensification with the bioethanol fermentation reaction as a typical example of product inhibition reaction, are introduced and discussed briefly.
