摘要

The different structures of double-layers

containing amorphous PDLA and highly oriented PLLA ultrathin films

with and without prior annealing at 150 C after melting at 190 C and then recrystallizing isothermally at 90 C have clearly illustrated the great impact of pre-annealing on the subsequent melt recrystallization behavior of them.

Abstract

Poly(lactic acid) (PLA) as a bio-based polymer with biodegradability and biocompatibility has attracted much attention. To manipulate its properties for different applications

regulation of crystal structure and crystalline morphology becomes an attractive research topic. In this work

the structure evolution of layered samples containing an amorphous poly(D-lactide) (PDLA) layer and a crystalline poly(L-lactide) (PLLA) layer with highly oriented edge-on

lamellar crystals after annealing at 150 °C or/and after melt-recrystallization has been studied by AFM

FTIR

and TEM combined with electron diffraction. The results demonstrate that melt recrystallization of the as-prepared sample leads to the formation of abundant randomly oriented PLA stereo-complex (PLA SC) crystals. Annealing at 150 °C results in the formation of a small amount of oriented PLA SC crystals at the interface. These PLA SC crystals show great impact on the recrystallization behavior of sample after melting at 190 °C and then crystallizing at 90 °C. First

they impede the mutual diffusion of the overlying PDLA and underlying PLLA

and thus reduce their stereo-complexation ability as manifested by the decreased amount of PLA SC crystals. Second

they act as substrate to initiate the epitaxial crystallization of the overlying PDLA and underlying PLLA

which ensures the production of a highly oriented structure of PDLA and PLLA after melt recrystallization again.
