Investigation the physico-mechanical, structural and thermal properties of films based on soy flour polysaccharide contain cloisite Na+

In this study, low soluble and mechanical-tension resistant nanocomposite films were developed by adding different concentrations (5, 10 and 15% dw) of nanoclay type Cloisite Na (CNa) to the soy flour polysaccharide. In order to investigate the physico-mechanical, structural and thermal properties of the developed nanocomposite, it has been synthetized by soluble molding method. When the nanoclaywas added to the biopolymer film, water solubility decreased, although the aforementioned trend was more significant when the concentration of the nanoclaywas raised. The film transparency was significantly declined when the nanoclay was added. By adding the nanoparticle, the film strength increased and this was increased when the nanoparticle concentration increased. Elongation at break decreased when the nanoparticle concentration was increased. The XRD results indicate that pure film specimen is amorphous whereas the biopolymer structure is becoming order and crystallinity increased when the nanoparticle was increased. These results revealed the peaks shifting to the lower degrees, increasing the interspace between nanoclaylayers and intercalation. From morphological point of view, a homogenous texture caused by adding nanoparticle to the polymer matrix was investigated using SEM. This study aimed to be successful for using the soy polysaccharide film as well as nanoparticle in order to introduce a new film in which used for nanocomposite synthetize.
