Investigation of Microstructure, Morphology, Mechanical, and Dielectric Properties of PVA/PbO Nanocomposites

Abstract

The present article deals with the preparation and characterization of pure and lead oxide (PbO) nanoparticles embedded polyvinyl alcohol (PVA) films by using a colloidal processing technique. PbO nanoparticles were successfully synthesized using the simple precipitation method. Polymer/ceramic-based flexible and self-standing films were obtained and further characterized using various analytical techniques. The mechanical and dielectric properties were also investigated. The Fourier Transform Infrared Spectroscopy (FTIR) results indicate that the structural characterization of PVA is strongly affected by the incorporation of PbO. Thermal analysis results indicate that the thermal stability of the PbO-doped PVA film has improved as compared with the neat PVA film. The mechanical property of nanocomposites has improved significantly due to an increase in filler loadings, indicating that a good interaction exists between PbO nanoparticles and PVA matrix. The dielectric constant of PVA/PbO nanocomposites has significantly improved with comparatively low dielectric loss values, indicating that the nanocomposites can be considered as an attractive material for embedded capacitor applications.

Study of double-using ultrasonic effects on the structure of PbO nanorods fabricated by the sonochemical method

“…Lead oxide nanostructures have four distinct semiconducting oxide forms, namely PbO, PbO 2 , Pb 2 O 3 , and Pb 3 O 4 . Among them, PbO possesses unique electronic, mechanical, and optical features, thus favored in nanodevices that can be crystallized in α and β phases [11] ; α-PbO (tetragonal phase or litharge) is stable at low temperatures and red in color, while β-PbO (orthorhombic phase or massicot) is stable at high temperatures and yellow in color [12] , [13] .…”

Electromagnetic interference shielding properties of graphene quantum‐dots reinforced poly(vinyl alcohol)/polypyrrole blend nanocomposites

“…[17] PNCs reinforced with conductive nanofillers such as graphene, graphene quantum dots (GQDs), carbon black, and exfoliated graphite nanoplatelets, exhibiting higher dielectric constant, large specific surface area, high carrier mobility, and excellent thermal and electrical conductivity are suitable as shielding materials. [18][19][20][21] In the present work, the poly(vinyl alcohol) (PVA) and polypyrrole (PPy) were chosen as a polymeric material and GQDs were used as fillers. PVA is the most interesting water soluble polymer because of its variety of applications.…”

Production of the ZnO-folic acid nanoparticles and poly(vinyl alcohol) nanocomposites: investigation of morphology, wettability, thermal, and antibacterial properties

“…Such as TiO 2 that is considered in fabrication of wave-absorbing composites [6] or Fe 3 O 4 , which is attracted the attention of researchers because of its strong magnetic and low electrical conductivity properties [7]. Different NPs have been used for the reinforcement of PVA NC films such as TiO 2 [8], Ag [9], PbO [10], Fe 3 O 4 [11], and so on. Among them, zinc oxide (ZnO) nanoscale has been considered for its superior features.…”
