The effect of titanium dioxide on the tensile properties of polycarbonate and polystyrene polymers

Abstract EN

This research study the effect of Titanium dioxide on the tensile properties of Polystyrene (PS) and Polycarbonate (PC) polymers.

The stress-strain curve for pure PS and pure PC, shows that Young modulus for PS is higher than Young modulus for PC, because PS have higher ultimate strength than PC.

The addition of TiO2 to PS and PC will reduce the Young modulus and ultimate stress, because the TiO2 particles will reduces or freeze the orientation of these molecular chain and reduced the toughness of PC, while when the TiO2 were added to PS, the value of toughness will be stabilized because TiO2 particles make these chains interlocked and the mobility of the chains will be restrict.
