在导电高分子薄膜表面沉积密度可控的银纳米粒子

<正>由于导电高分子的导电性和化学性质可以在导体和半导体区间内快速调节[1],因此其复合材料受到了越来越多的关注[2].金属纳米粒子在光电子器件、检测及传感等诸多领域表现出独特的性能[3],在生物技术领域中的重要性尤为突出[4].因此,如果将导电高分子和金属纳米粒子结合在一起,将有利于拓展导电高分子的应用范围.本文研究了银纳米粒子在聚苯胺薄膜表面的沉积行为,分别用原子力显微镜(AFM)和扫描电子显

Deposition of Silver Nanoparticles with Controllable Density on the Conducting Polymer Film

Deposition of Ag nanoparticle on the surface of polyaniline was discussed. Based on the electrostatic interaction,the Ag nanoparticles were deposited on the conducting polymer surface with controllable coverage by adjusting the deposition duration. Moreover,the selective deposition on the patterned polyaniline was performed. The noble metal nanoparticles are often employed in the biotechnology,and the combination of the nanoparticle and the conducting polymer may endow the conducting polymer more applicatio...
