Transtlate The paper written by the research group of Associate Researcher Li Haibin in School of Mechanical Engineering, which was published in the latest Macromolecular Chemistry and Physics (April 15,2010), was on the front cover of the magazine (DOI: 10.1002/macp.200900723). Macromolecular Chemistry and Physics was commenced in 1943 by Hermann Staudinger, the winner of the Nobel Prize in Chemistry, and has been published by John Wiley Press in Germany, focusing on original research papers in the field of macromolecular chemistry and physics. In the research conducted by Li Haibin’s team (“Ultra-thin, Free-standing Proton-Conducting Membrane with Organic/Inorganic Sandwich Structure”), an ultra-thin (600nm in thickness), free-standing proton-conducting membrane with organic/inorganic sandwich structure is prepared. In the sandwich structure, the middle inorganic SiO2 layer suppresses methanol permeation, while the lower and upper organic layers provide sufficient mechanical strength and flexibility. The rate of methanol permeation in the free-standing membrane with sandwich structure is lower than Nafion membrane. This research result offers new solutions for the problem of methanol permeation in polymer proton-conducting membrane which directly limits the development of methanol fuel-cells. Besides, the achievement is of great importance to develop ultra-thin electrolyte membrane applied in fuel-cells, sensors, and super capacitors.
