摘　　要：渗透汽化优先透醇膜分离技术可有效解决燃料乙醇和丁醇生产中发酵产率较低的瓶颈问题,受到广泛关注。膜材料的选择与改性以及膜结构的构建是提高透醇性能的关键。有机/无机杂化膜可以实现有机和无机材料的优势互补,被认为是未来分离膜领域最重要的发展方向之一。本文扼要回顾了用于优先透醇渗透汽化分离的有机无机杂化材料,结合本文作者课题组的研究工作,重点阐述了杂化粒子的结构、粒径、界面相容性、纳微分散、负载量等因素对渗透汽化传递过程的作用机制,进一步对近年来发展的成膜新方法进行了总结。在此基础上,提出今后有机/无机杂化渗透汽化优先透醇膜研究的主要方向是发展新型纳米级、超疏水并与有机聚合物具有高度界面相容性的无机粒子,以及构建高负载量的纳微结构与超亲醇表面。Alcohol perm-selective pervaporations membrane could resolve the product inhibition problem effectively for the use of ethanol and butanol recovery from fermentation process. The selection and modification of membrane material,and the construction of membrane structure are the key issues for better pervaporation performance. Organic/inorganic hybrid membranes combine the advantages of both organic polymers and inorganic materials,forming highly promising membranes for separation. This paper reviews the advances in organic/inorganic hybrid alcohol perm-selective pervaporation membrane materials. Several issues and research priorities which will impact the pervaporation ability of hybrid membrane for biofuel recovery are identified and discussed,including particle structure,particle size,compatibility and dispersion of inorganic particles in the polymer,and particle loading. Novel preparation methods in recent years are also presented in detail. Finally,the prospect of developing novel particles with nano size , superhydrophobic pores and polymer compatibility are presented,and the design ideas of constructing high loading,micro-and nanoscaled hierarchical structures with high affinity to alcohol are also illustrated.
