Epoxy groups on the surface of C25A were introduced by treating C25A with (glycidoxypropyl)trimethoxy silane (GPS) to produce so called Functionalized Organoclay (F-C25A). The silicate layers of PLLA/PCL/F-C25A were exfoliated to a larger extent than PLLA/PCL/C25A. Incorporation of the epoxy groups on C25A improved significantly mechanical properties of PLLA/PCL/C25A. The larger amount of exfoliation of the silicate layers in PLLA/PCL/F-C25A as compared with that in PLLA/PCL/C25A was attributed to the increased interfacial interaction between the polyesters and the clay due to chemical reaction. Thermo gravimetric analysis revealed that the nanocomposites with exfoliated silicate layers were more thermally stable than those with intercalated silicate layers. The biodegradability of the neat PLLA/PCL and corresponding nanocomposite was studied under compost, and the rate of biodegradation of PLLA/PCL increased after nanocomposite preparation.
