Polyaniline coated on tapered multimode fiber for ammonia sensing


Ibrahim @ Ghazali, Siti Azlida and Abdul Rahman, Norizah and Abu Bakar, Muhammad Hafiz and Yaacob, Mohd Hanif and Mahdi, Mohd Adzir (2014) Polyaniline coated on tapered multimode fiber for ammonia sensing. In: 5th International Conference on Photonics (ICP 2014), 2-4 Sept. 2014, Palace of the Golden Horses, Kuala Lumpur, Malaysia. (pp. 233-235).


This paper presents optical response of polyaniline coated on tapered multimode fiber towards ammonia gas. Polyaniline was deposited onto tapered multimode fiber by spray-coating method. Surface morphology of the coating was observed under scanning electron microscope. Absorbance measurement was done using spectrometer while the coated fiber was exposed to ammonia gas with concentration varies from 0.125% to 1% at room temperature. The absorbance is proportional to the ammonia concentration. The response and recovery time is 2.27 minutes and 10 minutes, respectively.
