Polylactic acid (PLA) is a biodegradable and biocompatible polyester derived from
renewable resources like corn starch, presenting great potential in clinical applications like
tissue engineering, implants and drug delivery systems. However, the intrinsic brittleness
restricts its real applications. In this work, PLA nanocomposites were prepared by
incorporating a small amount of carboxyl functionalized multi-walled carbon nanotubes
(CNTs) and surface compatabilized montmorillonite (MMT) via technologies of freeze-drying …
