“…The pressure sensor application of (PVA-PAA-PbO 2 ) nanocomposites was investigated by measuring the resistance between two electrodes on the top and bottom of the samples of (PVA-PAA-PbO 2 ) nanocomposites for different pressures (80-200) bar. The dc electrical specific conductivity ( ) of (PVA-PAA-PbO 2 ) nanocomposites in a sample is determined by the formula [14]:…”

This paper aims to the preparation of novel pressure-sensitive nanocomposites with low cost, light weight, and good sensitivity. The nanocomposites of polyvinyl alcohol, polyacrylic acid, and lead oxide nanoparticles have been investigated. The dielectric properties and dc electrical conductivity of (PVA–PAA–PbO2) nanocomposites have been studied. The dielectric properties of nanocomposites were measured in the frequency range (100 Hz–5 MHz). The experimental results showed that the dielectric constant and dielectric loss of (PVA–PAA–PbO2) nanocomposites decrease, as the frequency increases, and they increase with the concentrations of PbO2 nanoparticles. The ac electrical conductivity of (PVA–PAA–PbO2) nanocomposites increases with the frequency and the concentrations of PbO2 nanoparticles. The dc electrical conductivity of (PVA–PAA–PbO2) nanocomposites also increases with the concentrations of PbO2 nanoparticles. The application of pressure-sensitive nanocomposites has been examined in the pressure interval (60–200) bar. The results showed that the electrical resistance of (PVA–PAA–PbO2) pressure-sensitive nanocomposites decreases, as the compressive stress increases. The (PVA–PAA–PbO2) nanocomposites have high sensitivity to pressure.

We have synthesized a nanocomposite of a new type as a humidity sensor and studied its electric and optical properties. The carboxymethyl cellulose-starch-copper oxide nanocomposite is prepared with different concentrations of copper oxide nanoparticles. The DC electric conductivity of the carboxymethyl cellulose-starch-copper oxide system was tested at room temperature. The results show that the DC conductivity of the blend increases with the copper oxide concentration. The optical properties of the nanocomposite are measured in the range of wavelengths (220-800) nm. The results show that the absorbance of the blend increases with the concentration of copper oxide nanoparticles, whereas the energy band gap decreases. With the purpose to use the system as a humidity sensor, its electric capacitance was measured on different samples in the range of humidity (40-90) RH%. The experimental results have shown that the carboxymethyl cellulose-starch-copper oxide nanocomposite has a higher sensivity in the humidity range (60-90) RH%.
