Abstract

Polyaniline/Carbon Nanotube (PANI/CNT) composite films doped with dodecyl benzene sulfonic acid were synthesized by cyclic voltammetry on an ITO-deposited polyethylene terephthalate substrate. The SEM and FTIR were used to characterize the micro-morphology and chemical structure. The effect of CNT concentration on the electrical conductivity of the film was measured by a four-probe resistivity instrument. The electrochromic behavior of the composite film was characterized by a spectral photometer and an electrochemistry analyzer. The results show that CNTs act as a skeleton on which aniline can polymerize in the polymerization of PAN/CNT composite film. The film exhibits a porous network structure which can offer more approaches for electron transport and facilitate ion transmission. The cyclic voltammetry current density in the third polymerization cycle is the maximum because of the dense criss-cross network in the film. The CNT concentration takes great effects on the performance of PANI/CNT composite film, and the electric conductivity of the film improves with the CNT concentration rising within some limits. The CNT percolation threshold of the film is about 3.5wt.%. The PANI/CNT film polymerized at a CNT concentration of 2.5 wt.%, shows a reflectance change range of 38.8% at 540nm as well as a coloration efficiency of 386.4cm-2/C, which means that the PANI/CNT composite film has good behavior of voltage response.
