Abstract

In this study, the phase morphology of polycarbonate/poly(butylene terephthalate) (PC/PBT) blends was examined and the impact of chemical composition, molecular weight, and processing conditions on the phase morphology was determined. Through precise control of these variables, the researchers were able to create PC/PBT nano-blends with exceptional material properties and processing stability. The nano-blend showed remarkable fatigue and impact resistance, making it a strong candidate for use in mobile devices that are exposed to repeated stress and impact. The study also revealed that the PC/PBT morphology can be tailored from micro-scale to nano-scale by using the appropriate processing protocol, allowing for the desired properties to be achieved. The physical properties of the PC/PBT blends were explained in terms of their phase structures, thermodynamics, and kinematic principles.


Keywords: polycarbonate-poly(butylene terephthalate), nano-blend, fatigue resistance, phase morphology, processing.
