citric acid and
boric acid are not dangerous to use, however they have their
own drawbacks (Simkovic I, 2009).
In this study, after reducing hydrophilicity and swelling power of TPS by
applying suitable cross-linking method, a noticeable improvement is
observed, however, there is still a need to reinforce mechanical characteristics
of starch using specific additives. Several substances have been analyzed
and according to these investigations TiO
2
is one of the most efficient fillers.
Blending TPS with TiO
2
has improved the tensile strength and toughness of
material obviously. According to a study blending of TPS/TiO
2
with 1% TiO
2
had the best results for advanced mechanical properties. Adding TiO
2
at low
concentrations (0-3%) has changed the rheological characteristics and
crystalline behavior (Oleyaei S. A., 2016). As a consequence of this reinfor-
cement operation, the tolerance of TPS has been increased considerably and
application areas were expanded.
