论文摘要

It is still a challenge to achieve a high degree of stereocomplexation in enantiomeric polylactides with high molecular weight. This study demonstrates that gelation of enantiomeric polylactides in an ionic liquid, a non-volatile solvent, is a facile route to overcome this problem. The presence of the ionic liquid enhances the molecular mobility and mutual diffusion and thus to a large extent eliminates the kinetic barrier for stereocomplex formation. The gelation and stereocomplex formation in the ionic liquid may provide a new opportunity for the application of polylactides as scaffolds with high thermal stability in tissue engineering.
