摘要：
omega-(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 x 10(-4) cm(2).V-1.s(-1).
