“…The tensile strength of the cassava‐starch‐based film decreased significantly with increasing plasticizer content. The highest tensile stress was recorded for films with 30% fructose (4.7 MPa), which is higher than the 2.68 MPa reported for cassava starch plasticized with 30% glycerol and the 2.03 MPa for cassava starch plasticized with 25% glycerol , and similar to the result reported for 30% fructose with edible film . Films containing 60% TEA showed the lowest values for tensile stress (Fig.…”

The present study investigated the effects of plasticizers (fructose, urea, tri-ethylene glycol, and triethanolamine) with different concentrations on the physical, thermal, and mechanical properties of cassava-starch-based films. The film samples were prepared using casting methods. The moisture content, water solubility, and water absorption of the films increased with increasing plasticizer content. Fructose-plasticized films show excellent water resistance compared to other plasticizers. Film plasticized with 30% fructose showed the highest density (1.74 g/cm 3 ), but the lowest water content (10.96%) and water absorption (110%). Films containing fructose presented smooth surfaces without pores. The glass transition temperatures of the plasticized film also decreased with increased plasticizer content, irrespective of the plasticizer type. The relative crystallinity decreased with increasing plasticizer content. The film plasticized by 30% fructose presented higher relative crystallinity (0.31). The increase of plasticizer concentration resulted in a decrease of tensile strength, but increased elongation at break of the film samples. Film plasticized with 30% fructose showed the highest tensile strength (4.7 MPa) and tensile modulus (69 MPa). Thus, fructose was the most efficient plasticizer agent among the various plasticizers used in this study. High contents of plasticizer resulted in changes in the properties of the films. Overall, it can be concluded that the plasticizer type and concentration significantly influence the properties of cassava-starch-based film.

“…The main reason could also be ascribed the better interfacial compatibility between the MWCNTs and the chitosan matrix. Also, the glucose had plasticizer properties, which could form hydrogen bonds with the functional groups of the chitosan chains . By reducing the internal hydrogen bonding between the chitosan chains, we decreased the density of intermolecular interactions in the polymer chain and increased the free volume between the polymer chains.…”

“…Also, the glucose had plasticizer properties, which could form hydrogen bonds with the functional groups of the chitosan chains. 40 By reducing the internal hydrogen bonding between the chitosan chains, we decreased the density of intermolecular interactions in the polymer chain and increased the free volume between the polymer chains. Thus, the incorporation of MWCNT-Gl decreased the tensile strength and Young's modulus but increased the tensile strength of the 7 wt % CMG NCs because the higher aspect ratio and interfacial area made the stress transfer to the graphite sheet more effective and, consequently, improved the mechanical properties of the formed NCs.…”

A series of multiwalled carbon nanotubes (MWCNTs) grafted by chitosan nanocomposite (NC) films were prepared by a direct blending process and solution casting method. In this study, we modified multiwalled carbon nanotubes with glucose (MWCNT–Gl) for this purpose, and the effects of MWCNT–Gl on the structural, mechanical, and thermal properties of chitosan films with different contents of MWCNT–Gl were investigated. The structure, thermal stability, and mechanical properties of the composite were examined by X‐ray diffraction, Fourier transform infrared spectroscopy, field emission scanning electron microscopy, transmission electron microscopy, thermogravimetric analysis, and mechanical testing. The results indicate that the MWCNTs treated by glucose were dispersed well in the chitosan matrix, and the tensile properties of the NC films were improved greatly compared with neat chitosan. Also, with increasing MWCNT–Gl content, the crystalline nature of chitosan decreased. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 42022.

Los resultados mostraron un efecto significativo (p ≤ 0,05) en los valores del espesor de las películas a las dos concentraciones de quitosano. Se observó un efecto significativo (p ≤ 0,05) en los valores de humedad a concentraciones de 0, 200 y 400 ppm de aceite esencial. La adición de aceite esencial en películas de quitosano mostró un efecto significativo (p ≤ 0,05) en los valores de permeabilidad al vapor de agua. La concentración de quitosano mostró un efecto significativo (p ≤ 0,05) en transparencia y en los parámetros de color L*, a*, b*. Al variar la concentración de quitosano se observó un incremento significativo (p ≤ 0,05) en los valores de resistencia a la tensión de las películas de quitosano.Palabras clave: películas comestibles; quitosano; Cymbopogon citratus; propiedades mecánicas; color. AbstractThe effect of the incorporation of lemon grass (Cymbopogon citratus) essential oil at concentrations of 0, 200 and 400 ppm in the physicochemical (thickness, moisture, solubility, water vapor permeability, color, transparency) and mechanical properties (tensile strength and elongation) of chitosan films at concentrations of 1 and 3% was assessed. Results showed a significant effect (p ≤ 0.05) on the thickness values of films at concentrations of 1 and 3% of chitosan. A significant effect (p ≤ 0.05) was observed in the moisture content at concentrations of 0, 200 and 400 ppm of essential oil. The addition of essential oil to chitosan films showed a significant change (p ≤ 0.05) in the water vapor permeability values. The chitosan concentration showed a significant effect (p ≤ 0.05) on transparency and the L*, a*, and b* color parameters. By varying the chitosan concentration, a significant increase (p ≤ 0.05) in the tensile strength values of the chitosan films was observed.
