摘要: In this paper, a side polished multimode plastic optical fiber gas sensor coated with graphene/polyaniline nanocomposite is developed for ammonia sensing application. Graphene/polyaniline deposited onto by drop-casting method. The proposed exposed to different concentration of varies from 1% 0.25 % at room temperature. Absorbance response the monitored and recorded using spectrophotometer system. absorbance increase linearly in concentrations. recovery time are 24 s 71.8 s, respectively.
