Another set of films was prepared by pouring chitosan solution into Petri dishes and air drying
the samples a fume hood for 24 hrs. Samples were prepared from 1% and 2% chitosan solutions.
These films were cut into the dob-bone-shape and tested for their mechanical properties. Like the
gelatin samples that were dried in the fume hood, these samples formed concave films. Tables 4
and 5 and Figure 10 below show the results of tensile testing for these samples.
