The scientific community maintains considerable interest in polyvinyl alcohol (PVA) based on metal oxide nanocomposites due to its ability to combine both polymers and dopants with their properties. [1-15] These polymers have many applications in medical and engineering technology because of their mechanical, electrical, and optical properties. [16,17] ZnO-based polymeric nanocomposite materials have attracted scientific attention because of their transparency, high electron mobility, wide bandgap (3.2 eV, at 300 K [18,19]), and electrical properties. The insertion of ZnO nanoparticles into PVA matrices, in general, may significantly change their electric, mechanical, and optical characteristics. [1,7,8,15] PVA is readily water-soluble, and as such has many uses in the fields of polymer processing, pharmacy, and biomedicine. [20-23] Shanshool et al. [7] have studied the optical properties of various composites that use ZnO nanoparticles as a filler material in different polymer matrices, such as poly(methyl methacrylate) (PMMA), poly(vinylidene fluoride) (PVDF), PVA, and polystyrene (PS). ZnO nanoparticles have been found to have an effect on the bandgap of each polymer matrix, depending on the polymer's nature. The structural, optical, and dielectric properties of ZnOreinforced poly(ethylene oxide) (PEO) blended with poly(vinyl pyrrolidone) (PVP) have been previously studied by Choudhary. [13] It was noted that the enhanced optical properties of obtained nanocomposite films confirm the suitability of these materials for use in optical sensors. Moreover, Selvi et al. [1] synthesized ZnO nanoparticles with the co-precipitation method and reinforced a PVA matrix to investigate the optical and electrical properties of the resultant polymer composite films. However, the linear optical parameters, such as the refractive

A green synthesis approach has been adopted to prepare nickel sulphide nanoparticles (NiS NPs) using banana peel extract (BPE) as a reducing and capping agent. Polyvinyl alcohol (PVA)/NiS nanocomposite films were fabricated using a cost-effective solution casting technique by dispersing different contents of NiS NPs (0-3 wt%) in the PVA matrix. Various characterization techniques were employed to analyze the structural, thermal and morphological properties of the PVA/NiS nanocomposite films. Further, the dielectric behaviour of these nanocomposite films was investigated at frequency range 50 Hz-20 MHz and in the temperature range 40°C-140°C. Also, there exists a significant interaction between the polymer matrix and the nanofiller as evident from the notable improvement in the dielectric properties of the nanocomposites. The dielectric constant (ε) value of PVA/NiS nanocomposite film with 3 wt % NiS NPs loading was found to be 154.55 at 50 Hz and at 140°C which is 22 times greater than the dielectric constant value of neat PVA (6.90). These results suggest that NiS NPs were dispersed homogeneously in the PVA matrix.Among various polymers used for the fabrication of PNCs, polyvinyl alcohol (PVA) is most often preferred as a host matrix owing to its excellent film-forming ability, higher dielectric strength, the capability to form strong hydrogen bonding, easy processability, excellent chemical stability, and highly durable nature [17]. PVA has been employed for various applications such as in battery components, packaging, textile applications in the microelectronic industry, electromagnetic interference applications and so on [17,18]. Several research groups reported the dielectric properties of the PVA based nanocomposites [19][20][21]. With this inspiration, in the present study PVA has been chosen as a host polymer to synthesize PVA based nanocomposites. Now a day, more attention has been focussed on metal sulphide nanostructures because of their unique properties and applications [22]. Among these, nickel sulphide (NiS) has been mostly investigated because of its simple production, affordable price and high electronic conductivity [23,24]. It exhibits complicated electrical, optical, structural, compositional and magnetic phase behaviour [25]. Also due to the possession of multi-phases, binary Ni-S systems such as NiS 2 , Ni 3 S 4 , Ni 9 S 8 , Ni 7 S 6 , Ni 6 S 5 , Ni 4 S 3+x , Ni 3 S 2 , and Ni 3+x S 2 have become fascinated materials [26]. NiS NPs exhibit different shapes such as layer-rolled structures, urchin-like nanocrystallites, flower-like architectures, hollow spheres, nanoframes, nanorods, and nanospheres etc [27,28].Recently, increased attention has been given to the green approach for the synthesis of NPs because of its several advantages [29][30][31][32]. For the synthesis of NPs, the plant extracts which serve as reducing/capping agents are considered to be more beneficial than remaining techniques [33]. Several researchers reported the synthesis of metal sulphide NPs through a green synthesis a...

In this work, a deep insight is given into the dielectric properties and the humidity response of flexible polymer matrices, composed of polyvinyl alcohol (PVA) and glycerol (Gly), using silver nanowire networks as transparent electrodes (AgNW TE). These electrodes, known for their high electrical conductivity, optical transparency, and excellent flexibility, are deposited here by open‐air, scalable spray coating technique. Analysis of the dielectric constant ε′ and loss tangent tanδ according to the density of the AgNWs shows that the latter do not cover the entire surface with PVA and induces an interfacial polarization effect. Wide frequency range of impedance spectroscopy (1 Hz to 1 MHz) on both, PVA‐Gly samples with AgNW TE (4 Ω sq−1) networks electrodes and sputtered silver electrodes (Ag bulk el), reveal no significant change in ε′ and tanδ. Finally, the humidity sensing properties of PVA‐Gly exhibit good response between 20% to 90% humidity range and low hysteresis. This is related to the non‐continuous structure of AgNW TE. At 100 Hz, the PVA‐10 wt% Gly presents high sensitivity of 0.08 nF/% RH with an hysteresis value of about 1.5% at 70% RH. These results indicate that AgNW networks show great potential for integration in transparent and flexible humidity sensors.
