| 摘 要： | 含有不同的链长的w-吡咯烷基二甲基氯硅烷作为粘合剂通过自组装（SAMs）吸附于二氧化硅表面，然后聚吡咯膜化学沉积于该粘合剂修饰的表面。化学沉积的聚吡咯膜的表面形貌用扫描电镜（SEM）及原子力显微镜（AFM）表征。除短链外不同链长的粘合剂对聚吡咯膜的厚度影响不大。聚吡咯膜的电特性用电流-电压表征。结果显示电流与粘合剂的链长无关。电特性表明载流子迁移率为1.4 ´ 10-4 cm2×V-1.s –1。

| Abstract: | ω‐(Pyrrol‐1‐ylalkyl)dimethylchlorosilanes with different chain lengths were adsorbed on silicon oxide surface, subsequently, the polypyrrole film was deposited on this modified substrate. The chemical deposition of polypyrrole on the modified surface was investigated by SEM and AFM. The thickness of deposited polypyrrole films on different chain adhesion promoter modified substrates has no big difference except that of the short chain length. The electric properties were investigated by current‐potential characterization. The results show that the value of the electrical current does not monotonically depend on the length of the spacer of the adhesive monolayer. The electric property shows that the charge carrier mobility is 1.4×10?4 cm2·V?1·s?1. |
