摘要

Reactive compatibilization typically suppresses crystallization in polymer blends by reducing chain mobility and regularity

but this study reveals that under shear flow it instead significantly enhances the crystallization rate.

Abstract

Reactive compatibilization has been widely applied to enhance the compatibilit

y of polymer blends

thereby improving their mechanical properties. However

it generally reduces the chain mobility and regularity

often leading to slower polymer crystallization. Here

we demonstrate that reactive compatibilization in poly(lactic acid)/poly(butylene adipate-

-terephthalate) (PLA/PBAT) blends unexpectedly promotes PLA matrix crystallization during injection molding

in contrast to the retarded kinetics observed in differential scanning calorimetry isothermal crystallization studies. The phase morphology

rheological behavior

and crystalline structure were systematically analyzed to elucidate markedly different crystallization kinetics under static and shear fields. The potential mechanism underlying crystallization enhancement is attributed to PBAT domain refinement and viscosity increase induced by reactive compatibilization

which

under shear flow

create favorable conditions for crystallization by enhancing PBAT fibril nucleation and retarding the relaxation of oriented PLA chains. This study offers new perspectives on the effect of reactive compatibilization on the polymer crystallization behavior.
