Polymer-Plastics Technology and Materials

Poly(vinyl alcohol)/copper oxide/graphene nanoplatelets (PVA/CuO/Gr-NPls) nanocomposite based chemiresistive alcohol sensors were fabricated using colloidal blending method. The PVA/CuO/Gr-NPls nanocomposite films were characterized using Fourier transform infrared spectroscopy, X-ray diffraction, UV–Vis spectroscopy, thermogravimetric analysis, scanning electron microscopy, atomic force microscopy and the sensing behaviour of PVA/CuO/Gr-NPls nanocomposite films was evaluated for volatile organic compounds (VOCs). The improvement in the thermal, mechanical and VOCs sensing properties of nanocomposite film was observed attributing to the homogeneity of the nanocomposites and strong interfacial interaction between Gr-NPls, CuO and PVA matrix. The sensors were analyzed in the concentration range from 1800 to 4000 ppm. It was observed that PVA/CuO/Gr-NPls nanocomposite film exhibited excellent propanol sensing at a room temperature, typically at an applied voltage of 10 V when compared with other VOCs. Thus, the strong interaction between CuO and Gr-NPls helps in achieving excellent reinforcement effect in a PVA matrix for fabrication of high performance nanocomposite films for VOC’s sensing applications. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.

Influence of CuO nanoparticles and graphene nanoplatelets on the sensing behaviour of poly(vinyl alcohol) nanocomposites for the detection of ethanol and propanol vapors

The present article deals with the preparation and characterization of pure and lead oxide (PbO) nanoparticles embedded polyvinyl alcohol (PVA) films by using a colloidal processing technique. PbO nanoparticles were successfully synthesized using the simple precipitation method. Polymer/ceramic-based flexible and self-standing films were obtained and further characterized using various analytical techniques. The mechanical and dielectric properties were also investigated. The Fourier Transform Infrared Spectroscopy (FTIR) results indicate that the structural characterization of PVA is strongly affected by the incorporation of PbO. Thermal analysis results indicate that the thermal stability of the PbO-doped PVA film has improved as compared with the neat PVA film. The mechanical property of nanocomposites has improved significantly due to an increase in filler loadings, indicating that a good interaction exists between PbO nanoparticles and PVA matrix. The dielectric constant of PVA/PbO nanocomposites has significantly improved with comparatively low dielectric loss values, indicating that the nanocomposites can be considered as an attractive material for embedded capacitor applications. © 2015 Wiley Periodicals, Inc.
