Zhang Fengxiang is a researcher at the Institute of China Academy of Sciences.

Male, born in 1973. 1996 received a double bachelor's degree from the School of Chemical Engineering of Dalian University of Technology, graduated from the Department of Chemical Engineering and Biomolecular Engineering of National University of Singapore in 2005, and received a doctorate in 2006. From June 5438, 2005 to March 2009, he worked as a postdoctoral fellow and research engineer in the Agency for Science, Technology and Research (A * Star) of Singapore Research Council. In March 2009, he returned to Dalian Institute of Chemical Technology as an associate researcher.

The main research fields and achievements include: (1) design, preparation and performance research of high-performance polymer multilayer and hybrid membrane. The strategy of * * valence bond and * * valence/coordination layer by layer is mainly adopted to improve the stability of the film, and the polyimide homogeneous multilayer film, polyimide-polythiophene hybrid film and polyimide-gold nanoparticle hybrid film with solvent resistance, high temperature resistance and high mechanical strength are realized. (2) Nanostructures on the surface of polymer films. A continuous nano-imprint technique is developed, which can realize three-dimensional complex nanostructures on polymer surfaces. This structure can adjust the physical properties of the material surface, especially significantly change the hydrophobic/hydrophilic properties of the polymer membrane surface and the flow mode of water on the membrane surface. (3) Optimization of aminosilane assembly on the surface of materials. The influence of the molecular structure of aminosilane on the assembly behavior was revealed, and the primary amino rate of the assembled molecular layer was maximized. It is found that aromatic aminosilane can be assembled on the surface of silica in an orderly manner, and the primary amino ratio of the molecular layer obtained is close to 100%. This is of great significance for functionalization of material surface and immobilization of small molecules on material surface. In the above work, the first author published more than 0 scientific research papers 10 in international journals, and the papers were cited and reported by peers for nearly 80 times, and applied for 2 international invention patents.

At present, the main work is to develop new fluorine-free proton (ion) exchange membranes for fuel cells and liquid flow energy storage cells, so as to improve the conductivity stability and durability of the membranes and reduce the cost.
