Abstract

In this study, films based on two different polysaccharides (chitosan and cassava starch) were produced by casting technique and nanostructured by montmorillonite (MMTNPs) or bamboo nanofibers (BNFs) at two different concentrations: 0.5 g/100 g and 1.0 g/100 g of polymer, using glycerol as plasticizer at concentration of 30 g/100 g of polymer. The particle size and surface charge of the MMTNPs and BNFs nanoparticles were 315 +/- 14nm and 60 +/- 3 nm and -31.78 mV and -20.77 mV, respectively. In relation to the mechanical properties, the nanofibers increased the tensile strength in 50% of starch films, while the elongation at break shows a similar increase (66%) for both types of nanoparticles at concentration of 1.0 g/100 g. Cassava starch films showed a better response to nanostructure process, noticed through by the mechanical properties. XRD analyses showed good interaction between the polymer matrix and bamboo nanofibers. (C) 2017 Elsevier B.V. All rights reserved. (AU)
