Fabrication of Controlled Surface Properties of Poly(L-lactide) by Mixing with Lotus Leaf Powder

A biocompatible polymer composite film was prepared by casting method of the mixed solution of poly(L-lactide) (PLA) and lotus leaf powder (LLP) in chloroform. The obtained composite film showed hydrophobic properties. The surface wettability and change in the surface morphology of the film before a...

Description
Summary:A biocompatible polymer composite film was prepared by casting method of the mixed solution of poly(L-lactide) (PLA) and lotus leaf powder (LLP) in chloroform. The obtained composite film showed hydrophobic properties. The surface wettability and change in the surface morphology of the film before and after degradation in the enzyme solution were analyzed by contact angle measurement and high resolution scanning electron microscopy. The degradation rate of PLA could be controlled by mixing the right composition of LLP to PLA.
