Tóm tắt

Branched poly (butylene succinate-co-butylene terephthalate) (BPBST) was synthesized by in-situ polycondensation to enhance the foamability of poly (butylene succinate-co-butylene terephthalate) (PBST) and was blended with cellulose nanocrystals (CNC) to address foam shrinkage. The introduction of 2 wt% CNC increased the crystallization temperature of BPBST from 66.6 °C to 87.7 °C, accelerating its crystallization rate and improving both the mechanical properties and complex viscosity of the polymer matrix. Microcellular foams were produced using supercritical CO
