“…The ε 0 and ε 00 values of the PVA-based nanocomposites suggested that they can be used in electrostatic dissipation applications. 19 In addition to these studies, Martis et al tried to develop the optical and dielectric behavior of the PVA by embedding gold nanoparticles in the matrix. As a result of their experimental study, the presence of gold nanoparticles in the PVA matrix reduces the optical band gap energy and enhances both ε 0 and ε 00 .…”

In this study, it is aimed to produce a non‐carcinogenic and environmentally friendly biodegradable multi‐functional PVA‐based nanocomposite by improving its electrical properties and mechanical strength. For this purpose, BaO nanoparticles produced by the co‐precipitation method, have been added to the PVA matrix between 0.5% and 5% by mass, and thick film nanocomposites have been produced. The structural properties of the samples and the doping particle have been investigated by FTIR, SEM, and XRD. While electrical measurements have been carried out by an impedance analyzer at room temperature between 20 Hz and 15 MHz frequency, tensile tests have been performed by a mechanical tensile device. The addition of 5% BaO nanoparticles not only increased the energy storage capability of PVA significantly (117%) but also managed to reduce the loss factor considerably (77%). Moreover, compared to other samples, PVA/5% BaO nanocomposite also stands out with its higher ac conductivity within the mid‐and high‐frequency range. Furthermore, the 5% BaO nanoparticle additive provided a serious benefit to the mechanical strength of PVA by improving its Young's modulus, toughness, and stress at the break at different rates. As a result, the BaO nanoparticle additive makes PVA a more functional material as well as more technologically desired.

Tungsten delay systems widely used in mining and blasting operations which encourage the scientific research about improving the performance and reliability of these compositions. Binders' types and its percentage have a great effect in the performance of delay compositions. For this purpose, new research applied to different delay compositions which based on tungsten, BaCrO4, KClO4 and polyvinyl acetate (PVA) according to different percentage of (PVA). The PVA weight percentage varied from 5% to 15%. The compositions are fabricated by mixing, granulated and finally loaded in aluminium tube. Novel methods have been applied to predict the performance of delay element by ICT code. Which the resulted heat of formation and density have been illustrated. Ignition static test for delay element using central testing unit (CTU) by Schaffler company showed enhancement in burning rate by 7% to 37%. Characterization of the prepared compositions is carried out through sensitivity tests (impact, friction, ignition, electrostatic discharge (ESD) and thermal analysis test using DSC and TAM apparatus. All the obtained results from tested delay compositions ensure safety behaviour during handling, fabrication, transportation and storage.
