The phase behavior of polymeric materials is understood through glass transition temperature. It is a temperature boundary above which the polymeric material is soft and viscous, and becomes hard, brittle, and glassy below this temperature. In the present work, PS/PMMA immiscible polymer blend samples are studied at different compositional ranges. Thermal transport properties of PS/PMMA polymeric blends were measured , from room temperature to 120°C. Variation in thermal conductivity ...
The thermal and mechanical properties of PS/PMMA immiscible polymer blends were investigated. The effects of the dispersion of CdS nanoparticles on these properties were also investigated. The dispersion of the nanoparticles was found to result in an increase in glass transition temperature, as well as the thermal conductivity. The PS matrix was found to become more brittle and the PMMA matrix was found to become more compact upon the ...
The goal of this study was to determine how adding CdS nanoparticles to two polymer blends (PS/PVC and PS/PMMA) affects their thermal conductivities. Also, the effect of increasing the wt% of both PVC and PMMA in their respective blends was investigated. The thermal conductivity of the samples was determined through a transient plane method. The thermal conductivity of both polymer blends increased with the addition of CdS nanoparticles. ...
Cadmium sulfide (CdS) nanoparticles were dispersed in a polystyrene (PS) matrix to synthesize semiconducting optical nanocomposites for industrial applications. In this paper, many characteristics of the PS-CdS thick films were studied including thermal conductivity using the transient plane source (TPS) method. Results showed that the thermally conductive CdS nanoparticles enhanced the thermal conductivity of the nanocomposites....
