Mechanical and Thermal Transport Properties of PMMA/PC and PMMA/PS Blends

The present study deals with some results on mechanical and thermal transport properties of PMMA/PC and PMMA/PS polymer blends prepared by solution casting method at concentrations (0, 25, 50, 75, 100 wt%). Dynamic mechanical Analyser (DMA) and Transient Plane Source (TPS) technique have been used to measure the mechanical properties such as Young’s modulus, toughness, tensile strength, elongation at break and the thermal transport properties like thermal conductivity and thermal diffusivity of PMMA/PC and PMMA/PS blends, respectively, at room as well as elevated temperatures. Also the glass transition temperature (Tg) is determined with the help of DMA of these blended samples. The results show that the mechanical properties of PMMA/PC blends have improved significantly with the increase of PC content in PMMA polymer whereas PMMA/PS blend shows a decreased values of mechanical properties as compared to pure polymers.The Tan δ result shows a single glass transition for PMMA/PC blend which indicates a good...
