| Abstract: | Poly (e-caprolactone) (PCL) layered silicate nanocomposites have the advantage adding biocompatibility and biodegradability to the traditional properties of nanocomposites. They can be prepared by in situ ring-opening polymerization of e-caprolactone using conventional initiator to induce polymerization in the presence of an organophilic clay, such as organomodified montmorillonite. In this work, we have used an alternative method to prepare poly(e-caproilactone)/montmorillonite nanocomposites. The cationic polymerization of e -caprolactone was initiated directly by Maghnite-TOA, organomodified montmorillonite clay, to produce nanocomposites. Resulted nanocomposites were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), force atomic microscopy (AFM) and thermogravimetry. The evolution of mechanical properties was also studied.
