摘要

The improvement in segment mobility in poly(lactic acid) enantiomer blends can effectively enhance segment miscibility during the crystallization process

thereby promoting the formation of more stereocomplex crystals in poly(lactic acid).

Abstract

A fundamental prerequisite to effectively regulate the content of stereocomplex crystals (SCs) in poly(lactic acid) (PLA) is to elucidate the underlying mechanisms governing their formation. In this study

we established polymer blend systems with different chain segment mobility but similar initial segment miscibility based on dynamic Monte Carlo (MC) simulations. The SC fraction was found to be closely related to segment mobility in polymer blend systems during the crystallization process. The simulation results further indicated that polymer blend systems with stronger segment mobility exhibited higher segment miscibility during crystallization

resulting in the formation of more SCs. Therefore

it can be concluded that by increasing the segment mobility

segment miscibility can be enhanced

thereby improving the stereocomplexation ability.
