摘要

The effect of mechano-thermal field on morphology evolution of the PBAT/PBS co-continuous phase.

Abstract

Components of co-continuous phase can form an interpenetrating network structure

which has great potential to synergistically improve the mechanical properties of the blends

and to impart the functional blends superior electrical conductivity and permeability. In this work

the effects of shear rates (50−5000 s

−1

) at different temperatures on the phase morphology

phase size and lamellar crystallites of biodegradable co-continuous polybutylene terephthalate (PBAT)/polybutylene succinate (PBS) blend are quantitatively investigated. The results show that the above features of the PBAT/PBS have a strong dependence on the shear flow and thermal field. The co-continuous phase of the blend is well maintained at 130 °C. Interestingly

this phase structure transforms into a “sea-island” structure at 160 °C

which gradually recovers to a co-continuous phase when the shear rate increases from 1000 s

−1

to 5000 s

−1

. The phase size decreases with the increase of shear rate both at 130 °C and 160 °C due to the refinement and deformation of phase structures caused by strong shear stress. Unexpectedly

a unique phenomenon is observed that the shear-induced lamellar crystallites are oriented perpendicular to shear direction in the range of 500−5000 s

−1

at 130 °C

while the orientation of lamellar crystallites at 160 °C is along the shear direction within the whole range of shear rates. The degree of orientation for the PBAT/PBS blend crystals increases first and then decreases at both temperatures above. In addition

the range of shear rate has reached the level in the industrial processing. Therefore

this work has important guiding significance for the regulation of the co-continuous phase structure and the performance for the blend in the practical processing.
