Effect of the quenching temperature on the mechanical and thermophysical properties of polycarbonate pigmented with titanium dioxide

Abstract

Abstract This work deals with the effect of the quenching temperature on the mechanical and thermophysical properties of polycarbonate (PC) pigmented with titanium dioxide (TiO2). The thermal conductivity, thermal diffusivity, Izod impact strength and density measurements were measured. The thermal conductivity and diffusivity of the composites were measured using a periodic measurement method. It was found that an additional second quenching involved an increase in the value of the Izod impact strength near 35°C and a decrease in the values of the density, the thermal conductivity and the thermal diffusivity. A transition in these properties which is located at around 35°C has also been observed and linked to the β1 relaxation mode of PC.
