Solution-grown composite single crystals of poly(L-lactic acid)-b-polystyrene block copolymers and poly(L-lactic acid) homopolymers

In the present work, composite single crystals (CSCs) composed of poly (L-lactic acid) (PLLA) homopolymer and poly (L-lactic acid)-b-polystyrene (PLLA-b-PS) block copolymers (BCPs) were prepared by solution co-crystallization. The effects of crystallization temperature (Tc), mass ratio of BCP/homopolymer and PS block length on the morphology and growth habit of the CSCs were investigated. Particularly, parallelogram CSCs with four {110} crystal...
