Synthesis and Characterization of Novel Piezoelectric and Energy Storage Nanocompo-sites: Biodegradable Materials–Magnesium Oxide Nanoparticles

Section: Nanosystems
Original Author's Text: English

Abstract: Sensors based on piezoelectric polymer nanocomposites have high sensitivity, low weight, flexibility, low cost, etc. We have studied a novel piezoelectric sensor made of the carboxymethyl cellulose, polyvinyl pyrrolidone–magnesium oxide nanocomposite. The electric conductivity and dielectric properties of the nanocomposite are studied at room temperature. The dielectric properties of the nanocomposite are examined in frequency range (100 Hz–5 MHz). The DC electric conductivity, dielectric constant, and dielectric losses increase with the concentration of magnesium oxide nanoparticles. The dielectric constant and dielectric losses decrease, as the frequency increases. The AC electrical conductivity increases with the concentration of magnesium oxide nanoparticles and the frequency. The nanocomposite was tested for the piezoelectric application in the pressure interval (80–200) bar. The experimental results show that the electric resistance is decreased, as the compaction stress increases. The nanocomposite has high sensitivity to the pressure. The nanocomposites is tested for the thermal energy storage and release. The results indicate that the times of the melting and solidification in the thermal energy storage and release decrease, as the concentration of magnesium oxide nanoparticles increases.

Key words:  compaction stress, sensitivity, carboxymethyl cellulose, piezoelectric, conductivity, energy storage.
