Abstract: | Starch nanocomposites have been prepared using mineral clay. Montmorillonite, kaolin and a surface-modified montmorillonite
by dimethyl (hydrogenated tallow alkyl) ammonium cation were used. Starch-g-PCL nanocomposites have been prepared with graft
polymerization through in situ ring-opening polymerization of ε-caprolactone in the presence of starch, Sn(Oct)2 (Tin(II) 2-ethyl hexanoate) as an initiator/catalyst and silicate layers. In fact, the related composites were prepared in
solution method, bulk polymerization and in situ polymerization methods with introducing the mineral clay. The effect of kind
of clay on d-spacing of silicate layers was investigated and the obtained nanocomposites were analyzed using X-ray diffraction.
The obtained compounds were characterized by Fourier transform infrared (FT-IR). Morphology of the prepared nanocomposites
was investigated using scanning electron microscopy and DSC enhanced the study of thermal behaviour of the prepared composite
compounds. |
