Polyaniline Nanofiber Based Surface Acoustic Wave Gas Sensors—Effect of Nanofiber Diameter on H2 Response
A template-free rapidly mixed reaction was employed to synthesize polyaniline nanofibers using chemical oxidative polymerization of aniline. Hydrochloric acid (HCl) and camphor sulfonic acid (CSA) were used in the synthesis to obtain 30and 50-nm average diameter polyaniline nanofibers. The nanofibers were deposited onto layered ZnO/64◦ YX LiNbO3 surface-acoustic-wave transducers. The sensors we...
متن کاملDoped and Dedoped Polyaniline Nanofiber Based Conductometric Hydrogen Gas Sensors
Template-free, rapid polymerisation was employed to synthesize polyaniline nanofibers using chemical oxidative polymerisation of aniline, with HCl as a dopant. The doped and dedoped nanofibers were deposited onto conductometric sapphire transducers for gas sensing applications. The sensors were exposed to various concentrations of hydrogen (H2) gas at room temperature. The sensitivity was measu...
متن کاملA Layered SAW Gas Sensor Based on a Polyaniline/In2O3 Nanofiber Composite
A polyaniline/In2O3 nanofiber composite based layered surface acoustic wave (SAW) sensor has been developed and investigated towards different gases. Chemical oxidative polymerization of aniline in the presence of finely divided In2O3 was employed to synthesize a polyaniline nanofiber/In2O3 nanoparticle composite. The nanocomposite was deposited onto a layered ZnO/64° YX LiNbO3 SAW transducer. ...
متن کاملResponse Mechanism for Surface Acoustic Wave Gas Sensors Based on Surface-Adsorption
A theoretical model is established to describe the response mechanism of surface acoustic wave (SAW) gas sensors based on physical adsorption on the detector surface. Wohljent's method is utilized to describe the relationship of sensor output (frequency shift of SAW oscillator) and the mass loaded on the detector surface. The Brunauer-Emmett-Teller (BET) formula and its improved form are introd...
