Abstract
A template-free, rapidly-mixed reaction was employed to synthesize polyaniline nanofibers using chemical oxidative polymerization of aniline. Camphor sulfonic acid (CSA) was used in the synthesis to obtain 50 nm average diameter polyaniline nanofibers. The nanofibers were deposited onto a 64o YX LiNbO3 SAW transducer. The sensor was tested towards hydrogen (H2) gas while operating at room temperature. A fast response and recovery with high sensitivity and good repeatability were observed.
