Nanocomposite Thin Films

PANI-Ag-Fe nanocomposite thin films based electrochemicalE. colisensor was developed with thermal annealing. PANI-Ag-Fe nanocomposite thin films were prepared by oxidative polymerization of aniline and the reduction process of Ag-Fe bimetallic compound with the presence of nitric acid and PVA. The films were deposited on glass substrate using spin-coating technique before they were annealed at 300°C. The films were characterized using XRD, UV-Vis spectroscopy, and FESEM to study the structural and morphological properties. The electrochemical sensor performance was conducted usingI-Vmeasurement electrochemical impedance spectroscopy (EIS). The sensitivity upon the presence ofE. coliwas measured in clean water andE. colisolution. From XRD analysis, the crystallite sizes were found to become larger for the samples after annealing. UV-Vis absorption bands for samples before and after annealing show maximum absorbance peaks at around 422 nm–424 nm and 426 nm–464 nm, respectively. FESEM images show the diameter size for nanospherical Ag-Fe alloy particles increases after annealing. The sensor performance of PANI-Ag-Fe nanocomposite thin films uponE. colicells in liquid medium indicates the sensitivity increases after annealing.

Thermal Annealing Process

In this paper, a systematic spectroscopic analysis on silver–polyvinyl alcohol ( Ag /PVA) nanocomposite thin films is reported. Ag /PVA nanocomposite thin films fabricated by thermal annealing process are shown to exhibit a strong localized surface plasmon resonance (LSPR) at wavelength around 400 nm. The effects of different fabricating parameters on the absorbance and spectral position of LSPR are also investigated. The particle sizes calculated from Mie light scattering theory are found to agree with the values obtained from SEM characterization.
