Abstract
A series of polyvinyl alcohol (PVA)/starch
films were cast by the solvent method. Mechanical, optical,
wide-angle X-ray scattering (WAXS), and biodegradation
studies of starch-filled PVA films were carried out. With the
addition of starch there was an increase in haze and diffusion
of light, whereas there was only slight change associated
with tensile behavior and burst strength of the PVA
film. Microstructural parameters, such as crystal size (�N�)
and lattice distortion (g, in %) were estimated using onedimensional
Hosemann’s paracrystalline model along with
WAXS data. These parameters quantify the changes in the
PVA/starch systems, which resulted in the observed physical
properties.
