摘要
通过原子转移自由基聚合法(ATRP)在碳纳米管表面接枝聚甲基丙烯酸二甲氨基乙酯(PDMAEMA),得到表面修饰的碳纳米管(MWNT-g-PDMAEMA),进一步与二茂铁甲酸反应,成功制备了碳纳米管复合材料(MWNT-g-PDMAEMA/C11H10O2Fe).详细研究了碳纳米管复合材料(MWNT-g-PDMAEMA/C11H10O2Fe)修饰电极的电化学行为,结果显示碳纳米管复合材料(MWNT-g-PDMAEMA/C11H10O2Fe)修饰电极具有强烈的催化作用.
Poly[2-（N,N-dimethyl amino） ethyl methacrylate]（PDMAEMA） were successfully grafted onto the surface of multi-walled carbon nanotubes（MWNT） by atom transfer radical polymerization（ATRP） and modified multi-walled carbon nanotubes（MWNT-g-PDMAEMA） was prepared.Then MWNT-g-PDMAEMA/C11H10O2Fe composites were effectively obtained by further reaction of MWNT-g-PDMAEMA and ferrocenecarboxylic acid（C11H10O2Fe）.The electrochemical behavior of MWNT-g-PDMAEMA/C11H10O2Fe composites modified electrode was studied in detail and the results indicated that the MWNT-g-PDMAEMA/C11H10O2Fe composites modified electrode shows a strong catalytic effect.
