چکیده مقاله:
Nanocomposites based on Starch grafted-poly(caprolacton) (Starch-g-PCL) using in situ ringopening polymerization of ε-caprolacton in the presence of starch with Sn(oct)2 (Tin(II) 2- ethyl hexanoate) as an initiator/catalyst. A chemically nonmodified Na+-montmorillonite and surface-modified montmorillonite by dimethyl (hydrogenated tallow alkyl) ammonium cation, were used. In fact two methods in solution and in situ, with different amount loading clay was used in the preparation of nanocomposites. The effect of swelling time on d-spacing of silicate layers was investigated and the structure of nanocomposites were analyzed using Xray diffraction and the morphology of the prepared nanocomposites investigated using SEM (Scanning Electron Microscopic).
