| Abstract Scope |
High-entropy materials have high configurational entropy and excellent mechanical properties. In our study, we mixed four different thermoplastics by an in-situ exchange reaction process in appropriate moulds or reactors. Here, we evaluate the effect of the mould temperature on the mechanical properties of a high-entropy polymer blend. The blend includes PC, PS, PMMA, and PET. Melt mixing was conducted using a micro-extruder at a processing temperature of 270°C and moulded by an injection moulding process at 90°C, 110°C and 130°C. The resultant blend had a Tg between 110°C to 115°C. We found that as the mould temperature increased the Uts decreased. This blend under tensile stress exhibits small plastic deformation and this behaviour increases with increasing mould temperature. The cold-crystallization changes as the mould temperature changes. The results suggest that the mechanical properties of the blend are enhanced by this blending process and influenced by mould temperature. |
