摘要

We report structure-property relationships of polyaniline emeraldine base (EB) films that were produced by combining different processing steps in various sequences. The effect of annealing and doping processes on the surface structure of the films was investigated by atomic force microscopy (AFM), and the corresponding changes to the chemical structure of the EB films were monitored by Fourier transform infrared spectroscopy. AFM results indicate that after doping polyaniline (EB) films with HCl, the root mean square (rms) roughness of the surface of EB film increased approx 46%. When the doped polyaniline (EB) films were annealed, no electrical conductivity was observed. When these films were redoped, only approx 6% of the initial conductivity could be recovered. in another processing sequence in which the po9lyaniline (EB) films were first annealed and then doped, the electrical conductivity was only approdx 12% relative to the film that was doped immediately after being cast. From this work, a strategy to reduce the surface roughness of films made from electrically conducting polyaniline (EB) is proposed.
