In vitro degradation and cytocompatibility of g-MgO whiskers/PLLA composites

In vitro degradation properties and cytocompatibility of surface-grafted magnesia whiskers/poly(l-lactide) (g-MgO–Ws/PLLA) composite films which obtained by solution casting method were studied in this work. In vitro degradation experiments of the samples were carried out in a PBS solution at 37 °C with a pH of 7.4. Changes in weight, pH value, crystallization and melting behaviors, surface morphology and chemical composition, and tensile...
