摘要

Abstract

A biodegradable blend foaming material of poly(butylene adipate-

-terephthalate) (PBAT)/poly(propylene carbonate) (PPC) was successfully prepared by chemical foaming agent and screw extrusion method. First

PBAT was modified by bis(

tert

-butyl dioxy isopropyl) benzene (BIBP) for chain extension

and then the extended PBAT (E-PBAT) was foamed with PPC using a twin (single) screw extruder. By analyzing the properties of the blends

we found that Young's modulus increased from 58.8 MPa of E-PBAT to 244.7 MPa of E-PBAT/PPC 50/50. The viscosity of the polymer has a critical influence on the formation of cells. Compared with neat PBAT (N-PBAT)

the viscosity of E-PBAT increased by 3396 Pa·s and E-PBAT/PPC 50/50 increased by 8836 Pa·s. Meanwhile

the dynamic mechanical analysis (DMA) results showed that the storage modulus (

') at room temperature increased from 538 MPa to 1650 MPa. The various phase morphologies (“sea-island”

“quasi-co-continuous” and “co-continuous”) and crystallinity of the blends affected the spread velocity of gas and further affected the foaming morphology in E-PBAT/PPC foam. Therefore

through the analysis of phase morphology and foaming mechanism

we concluded that the E-PBAT/PPC 70/30 component has both excellent strength and the best foaming performance.
