“…Composite materials consisting of metal nanoparticles embedded in a transparent host matrix have attracted the attention of researchers recently as advanced technological materials such as solar cells for photoelectric conversion, transistors for electronic switches [1][2][3][4][5] because of their unique optical, electronic [6], mechanical [7] and structural [8] properties. Large interfacial area between the matrix and nanofiller is a key field of interest in nanocomposites since the nanomaterials possess high aspect ratio and large surface area [9].…”

The objective of this study was to investigate the effects of CuO nanoparticles on the structural, thermal and electrical properties of polyvinyl alcohol (PVA) thin films. The thin films were prepared by a solution casting technique with different weight percentages viz., 0.5, 1.0, 1.5 and 2.0 wt% of CuO nanoparticles in PVA matrix. The fabricated nanocomposite thin films were structurally characterised by Fourier transform infrared spectroscopy and X-ray diffraction, while differential scanning calorimetry indicated the effect of CuO nanoparticles on thermal properties of PVA. The surface morphology of the films was determined by scanning electron microscopy technique. Dielectric properties were analysed using high frequency LCR metre and were found to be dependent on frequency and CuO concentration. Dielectric constant decreased with increase in both frequency and CuO concentration. Dielectric loss increased with frequency increase and decreased with increase in CuO concentration. AC conductivity increased with increase in frequency. PVA-2.0 wt% CuO nanocomposite was found to possess desirable properties such as low dielectric constant and low dielectric loss which makes it a desirable material for use in microelectronics industry.

“…Polyvinyl alcohol (PVA) is a most preferred material of choice as a host matrix by various researchers [17][18][19][20][21][22] for the synthesis of polymer nanocomposites due its water soluble, non-toxic, ease of fabrication, transparent film forming ability, biodegradability, chemical stability and interesting mechanical properties. PVA is a semi-crystalline polymer with high optical clarity [20].…”

Zirconia toughened alumina (ZTA) nanopowder was synthesized by solution combustion technique. Polymer nanocomposites were prepared using ZTA nanopowder as the reinforcement and polyvinyl alcohol (PVA) as the matrix. ZTA nanopowder composition was varied from 0 to 2.5% by weight. Structural characterization was done using scanning electron microscope (SEM) and X-ray diffraction (XRD). XRD results showed prominent, well defined peaks of zirconia and α-alumina, hence confirmed that ZTA is a crystalline material. SEM images showed that, level of agglomeration kept increasing due to increase in filler content, which might have contributed to film stiffness. Thermal analysis was carried out using differential scanning calorimetry. Addition of ZTA into PVA matrix resulted in increase in melting point as well as glass transition temperature. Influence of the nanofiller concentration on the electrical conductivity was found using Agilent 4249A impedance analyser. Conductivity measurements were carried out for all the nanocomposite films doped with ZTA and were found to exhibit insulating properties. Change in mechanical properties such as Young's modulus, tensile strength and film toughness of PVA films as a function of nano filler content are reported.

In order to study the effect of nanocopper oxide (n-CuO) on the friction properties of fluorosilicone rubber (FVMQ), the mechanical blending method was used by adding n-CuO in preparation of FVMQ. Characterization of scanning electron microscopy, X-ray diffraction analysis, energy dispersive spectroscopy, and so on were utilized for studying the mechanism of n-CuO in FVMQ. The experimental test on tensile, tear, and friction performance were performed on n-CuO/FVMQ at both room temperature (RT) and 200 C. In comparison with n-CuO /FVMQ, the wear depth of FVMQ increased by 52.933 and 5.605 μm for RT and 200 C, respectively. Besides, the wear loss of FVMQ increased by 2.9 and 5.3 mg, respectively. The results show that for both at RT or 200 C, the addition of n-CuO changes the friction mechanism of FVMQ. The friction coefficient and wear loss of FVMQ are effectively reduced, so that the friction property of rubber matrix is significantly enhanced. In addition, the tearing property of FVMQ is improved by adding n-CuO to change the crosslinking density of FVMQ.
