Novel tertiary nanocomposite films comprising of poly (vinyl alcohol) (PVA), poly (4-styrenesulfonic acid) (PSSA) and titanium dioxide (TiO2) nanoparticles (NPS) were prepared using simple solvent casting method. The structural, thermal, morphological, thermo-mechanical and electromagnetic interference (EMI) shielding properties of PVA/PSSA/TiO2 nanocomposite films were investigated. The EMI shielding effectiveness (SE) of PVA/PSSA/TiO2 nanocomposite films in the X and Ku band was found to be 12 dB and 13 dB respectively at 25 wt% TiO2 NPs loading. These results demonstrate the possible applications of PVA/PSSA/TiO2 nanocomposite films as low cost, lightweight and flexible material for EMI shielding. © 2019, © 2019 Taylor &amp; Francis.

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.
