In this study, we prepared Polyvinyl chloride (PVC)/Nitrocellulose (NC) polymer blend by the solution casting technique. The structural properties and decreased interplanar spacing and crystalline nature of the PVC/NC blends were confirmed by an XRD technique. Basic chemical fingerprint regions of PVC/NC blends were confirmed by the Fourier transform IR method. Optical properties correlated with a decreased direct and indirect bandgap energy of PVC/NC were estimated using UV–visible spectra. They exhibited a shift in the absorption spectra towards the longer wavelength region due to process of charge transfer in the blend system. An increased microporous nature of the blends was demonstrated by SEM. Based on the Maxwell–Wagner model the dielectric constant and relative loss were found to have a maximum in the low frequency region which may be contributed by the polar nature of NC. We confirmed the hydrophilic nature of the PVC/NC blends due to the presence of hydroxyl groups by the goniometer technique. The thermophysical properties of the blends were measured by Lee's disc method. NC loading in the blend system increased the thermal conductivity from 0.12 to 0.18 W/(m.K). The Shore A softness test of the blends exhibited an 18% increase. We quantified structure, bandgap, morphology, and dielectric, surface and thermal properties as a function of NC blending. This new emerging blend may be a remedy for various engineering applications. © 2022 Society of Industrial Chemistry.

“…Air plasma treatment induces polar groups on the surface of the target material that improve the modified structure. 2 The influence of plasma exposure on crystallinity and interplanar spacing was confirmed by XRD, which could be one of the reasons for the improvement of the softness. Hence, the durometer test proved the influence of plasma treatment on the physical properties of nanoblends.…”

“…Some common polymers such as poly(tetrafluoroethylene) (PTFE), polyvinylidene fluoride (PVDF), and polydimethylsiloxane (PDMS) exhibit superior hydrophobicity, and their applications are also limited. Modification of such surfaces reduces hydrophobic nature and improves surface characteristics, which fit for extended applications [22].…”

The work is focused on the study of surface plasma treatment (DCSBD) of films from biodegradable polymers from renewable sources based on polylactic acid (PLA) and polyhydroxybutyrate (PHB). A 4-factor design of experiment was used where the selected variable parameters were the plasma device power, the time of plasma treatment, the ratio of PHB in the polymer blend with PLA, and the content of acetyl tributyl citrate (ATBC) plasticizer in the PLA + PHB blend. The surface total energy and the polar component were evaluated immediately after surface plasma treatment and after 5 h of sitting. Topography of foil surfaces was also studied by AFM. In terms of plasma power and activation time, the greatest increase in surface energy values was observed with a short plasma time of 2 s and a high power of 400 W. Increasing the content of ATBC in interaction with the high concentration of PHB in the blend results in a reduction in the difference of both the polar component and the total free surface energy.
