中文摘要	The production of renewable ethanol biofuel from fermentation process as well as the investigation of energy-saving separation technics is advanced by the energy crisis 1970s. As a rising membrane separation technology, pervaporation(PV) is especially attractive in the separation of azeotropic Mixtures such as ethanol/water mixtures due to high separation efficiency, low energy consumption, integration of pervaporation with fermentor and synergy of performing pervaporation and other separation methods etc. A brief introduction of investigation background of ethanol perm-selective membrane by pervaporation is given in this paper. Theories used for the selection of ethanol perm-selective membrane materials are summarized and analyzed. And the structure characteristics, modification methods and PV performance of ethanol perm-selective membrane materials (such as silicon-containing polymers, fluorine-containing polymers, organic/inorganic composite membrane materials and other polymers, etc.) with separation priorities are presented in detail. The relationship between the structure characteristics of PV membrane materials and their separation performance is discussed in detail. The pervaporation performance of various ethanol perm-selective membranes is summarized and compared. Problems existed in PV membrane for ethanol/water separation is proposed based on discussion above. And the foresight of development and investigation of ethanol perm-selective PV membrane is also brought forward.
