摘要：

Water soluble poly( aniline) was prepared using the chemical oxide method by adding a small amount of poly( sodium-p-styrenesulfonate). Poly( aniline) composite film on interdigital electrodes of carbon was formed via the spin-coating approach. After pretreatment of exposure in an alkalescence atmosphere and desorption with high-purity N-2, the film showed an excellent sensitivity to trimethylamine of 5.14 x 10(-7) mol mL(-1). Moreover, this film also had a good selectivity to analogous gases and a fast response while exhibiting a good reproducibility. It was easily recovered by high-purity N-2.
