“…Obviously, the slightly greater weight loss of the CdSNPs@NPAN‐rGO‐PAN complex is due to the presence of oxidizing ingredients in rGO, which promote the affiliation of water molecules. [ 45 ] Second stage, the weight loss is between 250°C and 425°C, which is thanked to the vaporization of HCl leading to NPAN deprotonation, [ 35 ] and the functional oxygen groups of rGO began to degrade slowly at this stage. Third stage, NPAN is completely degraded at about 425–610°C, and the thermal stability of CdSNPs@NPAN‐rGO‐PAN film was better than that of CdSNPs@NPAN‐PAN film, which is related to a small quantity of oxygen‐containing groups of graphene, hydroxyl group, carbonyl group, carboxylic acid, epoxy.…”

Modified optical fiber sensors received increasing attention because of their superior properties over electrical sensors. These properties include their immunity towards electromagnetic interference and the ability to be deployed in corrosive and volatile environment. Several optical fiber platforms have been developed for chemical sensing applications based on modifying optical fiber cladding layer such as etched, tapered, D-shaped and etched-tapered. The modifications purpose is to extend the evanescent wave propagating out of the core physical dimensions. Thus, evanescent wave interaction with analyte is enhanced. Modified optical transducing platforms are integrated in gas sensing applications, such as ammonia. Modified optical fiber sensors coated with nanostructured thin films have been developed and gained popularity as practical devices towards gases with low concentrations. The development and characterization of the modified SMF sensing platforms including etched, tapered and etched-tapered platforms against ammonia will be presented in this chapter. These platforms were coated with PANI nanostructured thin film. The 50 μm etched-tapered SMF coated with PANI produced response, recovery times, and sensitivity of 58 s, 475 s, and 231.5%, respectively, in the C-band range. The limit of detection of the modified fiber sensor was 25 ppm. The developed sensors exhibit good repeatability, reversibility, and selectivity.

The increased deployment of optical fiber sensors along with the development of internet of things has increased the demand for real-time in situ remote monitoring systems in the optical sensing industry. Etched-tapered single-mode optical fiber (ETSMF) sensors coated with polyaniline nanofiber/graphite nanofiber (PANI/GNF) nanocomposites have been developed for the real-time in situ remote monitoring of NH3. In this investigation, the sensors with a reel of SMF with 3 km length were integrated with Erbium-doped fiber amplifier (EDFA) with 15 dB gain. Modification performed on SMF significantly enhanced the interaction between the PANI/GNF sensing layer and the evanescent wave due to the light that propagates from the core layer. The response of the modified fiber sensor to NH3 with different concentrations over the C-band (1535-1565 nm) was investigated. The integration of EDFA into SMF sensors extended the remote monitoring distance. In the C band, the developed sensor showed the response, recovery time, and sensitivity of 59 s, 461 s, and 210, respectively. ETSMF sensors coated with nanocomposite of PANI/GNF exhibit successful remote-sensing performances.
