Regulation on rates of mass transfer, reaction and separation via smart membranes

智能膜能响应外界刺激而改变自身的表面特性和膜孔大小,从而改变其选择性和渗透性等性能参数,是化工与材料等交叉学科领域的重要课题。综述了近年来有关智能膜用于跨膜传质过程的调控、亲和分离过程的调控、催化反应过程速率的调控等方面的研究。基于智能膜的传质、反应与分离过程具有条件温和、易于操控、易调控、高效等特点,为简单、高效的传质分离与反应操作提供了新途径和新方法。

Smart membranes change their surface wettability and pore size, and thus selectivity and permeability in response to the environmental stimuli, which are active topics of interdisciplines based on chemical engineering and materials science etc. The recent studies on the regulation of trans-membrane mass transfer and catalytic reaction rates as well as affinity separation efficiency based on smart membranes have been reviewed. Such processes provide attractive features such as mild condition, easy operation and regulation, and high efficiency, which provide new ways to achieve simple and high-efficient operations of mass transfer, separation and reaction.
