Abstract： |
The nanometer carbonic anhydrse grain for biological catalysis of polymer and its preparation process belongs to the field of chemical modification of enzyme. The nanometer carbonic anhydrse grain with bioactivity is a core-shell structure with core of carbonic anhydrse, shell of crosslinked polymer material and chemical bond connection between the core and the shell, and possesses high catalytic activity, high heat stability and no aggregation. This kind of nanometer carbonic anhydrse grain has wide application foreground in CO2 absorption and separation and artificial lung system, etc. Its preparation process includes introducing C-C double bond radical with enzyme modifier to the surface of carbonic anhydrse and subsequent free radical polymerization with the olefin monomer with C-C double bond as material. |
