摘　　要：该工作制备了碳纳米管/聚苯乙烯-共-N-聚异丙基丙烯酰胺纳米粒子(CNTs/PS-coNIPAm),利用其修饰玻碳电极(GCE)发展了高灵敏的过氧化氢(H_(2)O_(2))电化学传感器。通过扫描电子显微镜(SEM)和循环伏安曲线(CV)对制备的修饰材料进行了表征。结果显示,CNTs/PS-coNIPAm修饰电极具有较大的比表面积和优异的电催化活性。与裸电极相比,修饰后的GCE电极对H_(2)O_(2)显示出明显提高的电流信号。CNTs/PS-co-NIPAm为发展新型电化学传感器提供了一条有前景的电极材料。Carbon Nanotubes-Poly(styrene-co-N-isopropylacrylamide)Nanoparticles(CNTs/PS-co-NIPAm)was for the first time used to modify glassy carbon electrode(GCE)for electrochemical hydrogen peroxide(H_(2)O_(2))sensor.The modified GCE was characterized using scan electron microscopy(SEM)and cyclic voltammetry(CV).The CNTs/PS-co-NIPAm modified electrode has larger specific surface area and excellent electrocatalytic activity.The peak current of H_(2)O_(2) was obviously improved at modified GCE compared to bare electrode.The proposed CNTs/PS-co-NIPAm provides a promising electrode material to develop novel electrochemical sensors.
