Another systematic study on PCL nanocomposites
was performed on the influence of different percentages
of MMT, degree of MMT intercalation, and different
organic modifiers of MMT on the diffusion coefficient
of dichloromethane [86]. For the organic solvent
(dichloromethane) diffusion, the intercalated samples
showed lower values of the diffusion parameters. This
result confirms that it is not only the content of clay but also
the type and size of dispersion of the inorganic component
in the polymer phase that is important for improving the
barrier properties of the samples.
