摘要

本文介绍了壳聚糖多孔膜的成功制备,它具有较好的力学、热、化学性能,可应用于水处理领域。采用溶剂浇铸法制备了带有交联剂和多孔剂的壳聚糖/高岭土复合膜。制备的膜的表征表明,在壳聚糖基体中,高岭土作为补强剂,聚乙二醇作为成孔剂,柠檬酸作为交联剂的复合作用对膜的性能有显著影响。结果表明,在胶体中掺入亲水致孔剂除了提供多孔形态外,还可以获得更亲水的膜,从而诱导纯水渗透性的增加。与纯壳聚糖膜相比,交联膜具有更好的耐水性、热性能和力学性能。交联膜的平均孔径为50 nm,在超滤范围内。通过纯水过滤和分子量切断试验确定了它们的功能特性。

Fabrication, Characterization and Permeation Studies of Ionically Cross-linked Chitosan/Kaolin Composite Membranes
This paper presents the successful preparation of porous membranes based on chitosan with enhanced mechanical, thermal and chemical properties applicable in water treatment field. Herein, chitosan/kaolin composite membranes with a cross-linking agent and a porogen were prepared using the solvent casting method. The characterization of the as-fabricated membranes indicated that the combined effect of kaolin as reinforcing agent, polyethylene glycol as pore former and citric acid as cross-linker in a chitosan matrix showed a significant influence on the membrane properties. The results indicated that the incorporation of a hydrophilic porogenic reagent into the collodion in addition to providing a porous morphology makes it possible to obtain a more hydrophilic membrane, and thus induces an increase in the pure water permeability. The cross-linked membranes exhibited an improved water resistance, better thermal and mechanical properties as compared to neat chitosan films. The cross-linked membranes had a mean pore size of 50 nm falling in the range of ultrafiltration. Their functional properties were determined in terms of pure water filtration and molecular weight cut-off tests.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
