“…Specifically, there was a diffraction peak at around 8.44° observed in the control films, in accordance with one previous study (Ziani, Oses, Coma, & Mate, 2008). The diffraction peak at around 11.54° was attributed to the anhydrous crystalline, and the diffraction peak at around 18.34° was the hydrated crystal character (Mathew, Brahmakumar, & Abraham, 2006).…”

“…Shen et al, 28 em filmes elaborados com batata doce e glicerol, observaram que a tensão na tração diminuiu progressivamente conforme ocorria a elevação de sorbato de potássio além de 5%, sendo o mesmo fato observado por Flores et al, 33 trabalhando com filmes de amido de mandioca e sorbato de potássio. Ziani et al 37 elaboraram filmes de quitosana sem glicerol e verificaram que estes apresentaram maior tensão na tração. Assim, a presença de glicerol em filmes de quitosana resultou em uma diminuição da tensão na tração em torno de 65%.…”

“…Thus, as expected, D-sorbitol addition increased WVP by increasing the free volume and enabling water vapor molecules to diffuse easily through the polymer chains. Ziani et al 14 also reported significant increase on WVP of chitosan films plasticized with glycerol.…”

“…However, these films can be brittle and fragile, mainly after the neutralization process that removes residual acids from the films. Plasticizers, such as ethylene, polyethylene and propylene glycol and other polyols, has been used to improve physical and mechanical properties of chitosan films [12][13][14] . In this study, we used D-sorbitol, a biocompatible polyalcohol, as plasticizer to prepare a non-cytotoxic chitosan membrane with interesting properties for skin substitute and tissue engineering applications.…”
