New Progress Made in Application of Low Temperature Plasma Technique for Preparation and Functionalization of Nano-materials

The Plasma Application Division of ASIPP has made new progress on preparation and functionalization of nano-graphene with low temperature plasma technique recent days. Compared to conventional methods, plasma technique can simplify the preparation process, does not produce chemical pollutant or alter the material bulk properties.

　  Nano-materials can be induced and grafted with different functional groups under different gas plasma. The functionalization of nao-materials can enhance their adsorption capacities for organic and irorganic pollutants, and can selectly remove some of these pollutants. Moreover, nano magnetic composites can be separated from solution by magnetic separation, thus shunning the difficult problem of solid-liquid separation due to small nano-size.

　  The related works are published in Applied Physics Letters, The Journal of Physical Chemistry C/B, Chemosphere, Plasma Processes and Polymers, Journal of Hazardous Materials etc. Two of them are selected as cover papers of Plasma Processes and Polymers. Prof. R. F?rch, editor of Plasma Processes and Polymers, comments: “graft modification of nano-materials with plasma technique is very important and very urgent”. (Chen Changlun Reports)

　  The project of preparation and functionalization of nano-materials with low temperature plasma technique is supported by the National Basic Research Program (also called 973 Program) of Ministry of Science and Technology (MOST) and Natural Science Foundation of China. (Chen Changlun Reports)
