Impact of Cold Plasma on Structural, Morphological, and Dielectrical Characteristics of Nanocomposites (PVA/PAA/Ag) Films

Abstract

A nanocomposites of (PVA/PAA/Ag) was prepared by casting method in different concentration of the nanomaterial (Ag) represented by (0, 2, 4, 6, and 8( wt.%. The structural, morphological, and electrical characteristic were studied. The optical microscope (OM) proved the Ag NPs create a continuous network within the blend and the formation of pits and grooves, which indicates sufficient energy in the Ar plasma gas to extract this substance which noted at (PVA/PAA/8wt.% Ag) nanocomposites. The FTIR spectrum of the functional collections existing in polymer nanocomposite systems were established, and changes in shifting and transmittance were observed as a effect of the adding of Ag NPs. The (PVA/PAA/Ag) nanocomposites films have a homogenous and coherent surface morphology, as revealed by SEM. Argon plasma species on the (PVA/PAA) surface provide a progressive impression, which leads to a diverse morphology. Dielectric constant, dielectric loss, and alternating current (A.C) electrical conductivity of (PVA/PAA/Ag) nanocomposites are found to rise with rising concentrations of Ag NPs, while decreasing with increasing frequency. Plasma interaction with the molecular structure of these nanocomposites results in increased values for the dielectric constant, dielectric loss, and alternating current (A.C.) electrical conductivity following irradiation. Finally, the results demonstrated that cold plasma's impact on nanocomposites could produce materials with broad applications in nanodevices for cutting-edge electronics.
