| Abstract: | A novel surface imprinting material based on multi-wall carbon nanotubes(MWNT/MIPs) modified with polyethylene glycol was successfully synthesized with a precipitation polymerization method by using ursolic acid(UA) as template,methacrylic acid(MAA) as functional monomer,and ethylene glycol dimethacrylate (EGDMA) as cross-linker.The MWNT/MIP was characterized by IR and scanning electron microscopy (SEM).The results showed that a stable,uniform imprinted materials layer was grafted on the surface of MWNT.The... |
