摘要：
The technique of surface plasmon resonance has been used to characterize Langmuir-Blodgett films of polyaniline. The thickness per layer obtained by curve fitting was 5.5 +/- 0.6 nm. The surface plasmon resonance curves have been shown to be influenced by both NO2 and H2S. The effects were partly reversible, with lower detection limits of about 50 vapour parts per million at room temperature. (C) 1997 Elsevier Science S.A.
