خلاصه مقاله:
Starch-g-polycaprolacton (Starch-g-PCL) nanocomposites were prepared through graft polymerization in situ ring-opening polymerization of E-caprolacton in the presence of starch, by using Sn(oct)2 (Tin(1) 2-ethyl hexanoate) as an initiator/catalyst. A nonmodified Na+-montmorillonite and surface-modified montmorillonite by dimethyl (hydrogenated tallow alkyl) ammonium cation, were used. In fact related nanocomposites were prepared through two methods in solution and in situ, with different amount loading clay. The effect of swelling time on dspacing of silicate layers was investigated and nanocomposites were analyzed with X-ray diffraction and morphology of the prepared nanocomposites investigated using SEM (Scanning Electron Microscopic
