“…56,57 As a result, modification of the phonon mean free path is due to elastic disorder and chain defect scattering of the phonons caused by weak hydrogen bonding in the polymer blend. 21 Along with thermal conductivity (k), the thermal diffusivity (⊍) and specific heat capacity (Cp) are also significant for thermal transport qualities; in the polymer sector these thermophysical parameters play a big role in calculating heat transfer. 58 ⊍ is a measure of how efficiently heat propagates through a material.…”

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.

“…Actually the knowledge of thermal properties is required prior to any potential application as the environmental and thermal stability of the material should be known to identify the optimal condition for the performance of a device. The thermal conductivity is that thermal property which is required to describe the heat transfer through the material (Patidar and Saxena 2013).…”

The effect of dispersion of CdS nano-filler particles in respective PS/PVC and PS/PMMA polymer blend matrices on the effective thermal conductivity has been studied through Hot Disk Thermal Constant Analyzer based on transient plane source (TPS) technique. The thick film samples have been prepared by dispersing nano-filler particles of CdS (6 wt%) in respective PS/PVC and PS/ PMMA binary blend matrices. The nanocomposite nature of prepared samples ascertained through small angle X-ray scattering (SAXS) as well as transmission electron microscopy (TEM) measurements. It is observed that at room temperature nano CdS dispersed polymeric blend samples offer higher effective thermal conductivity.

Thick film of Polystyrene (PS)/CdS semiconducting optical nanocomposite has been synthesized by dispersing nanofiller particles of CdS in PS matrix. The nanostructure of the CdS particles has been ascertained through X-ray Diffraction (XRD) and Transmission Electron Microscopy (TEM). Small angle x-ray scattering analysis has been performed in order to ascertain nanocomposite character of the PS/CdS sample. Scanning Electron Microscopy (SEM) analyses of these samples have been carried out to establish the surface morphology. Optical Absorption Spectroscopy is used to measure the energy band gap of PS/CdS nanocomposite by using Tauc relation whereas Transient Plane Source Technique is used for the determination of thermal conductivity of the prepared samples. The phase transition temperature and elastic response of the prepared samples have been ascertained through Dynamic Mechanical Analyzer (DMA). This study reveals that the thermal conductivity, Young’s modulus and the toughness of the material are greatly influenced by the existence of interfacial energetic interaction between dispersed CdS nanofiller particles and matrix of PS.
