摘要

SC crystallite fibers

as nucleating agent and reinforcing agent

will not sacrifice the transparency and degradation of PLLA

which provides a strategy for obtaining transparent PLLA-based composite films with synchronous enhancement of crystallization and mechanical properties.

Abstract

Poly(L-lactic acid) (PLLA) has been widely concerned because of its excellent biodegradability and biocompatibility. However

the poor crystallization ability of PLLA during the molding process not only leads to weak mechanical properties but also reduces the processing efficiency

which limits the application of PLLA greatly. Enhancing crystallization ability of PLLA

via

introducing inorganic nanoparticles usually sacrifices biodegradability or transparency. Here

the microfine fibers with stereocomplex (SC) crystallites were incorporated into PLLA film to tailor the crystallization ability of PLLA as well as the mechanical properties. The results confirmed that the crystallization ability of PLLA matrix under different circumstances could be greatly enhanced by a few amounts of

SC crystalline fibers

and synchronously enhanced tensile strength and ductility were also achieved

especially at relatively high temperature. Due to the relatively homogeneous dispersion of SC crystalline fibers and the similar refractive index between components

the PLLA-based film also exhibited high transparency

up to 85%-90% depending on the content of SC crystalline fibers. This work provides guidance for manufacturing transparent PLLA-based packaging materials with good crystallization capability and mechanical properties.
