| In the present study, new biodegradable nanocomposite films were produced. The effect of 30 wheat gluten (WG) (1-2.5 wt%), carboxymethyl cellulose (CMC) (0.5-1 wt%) and cellulose 31 nanofiber (CNF) (0-10 wt% based on gluten and CMC biopolymers solid matter in each formula) 32 concentration on water vapor permeability (WVP), mechanical and color properties of the 33 biodegradable nanocomposites were investigated using response surface methodology (RSM). 34 Regression models were also developed for all responses as a function of linear, interaction and 35 quadratic terms of WG/CMC/CNF concentrations. The optimum point with 1wt.% gluten, 0.686 36 wt.% CMC and 8.549 wt.% CNF for a maximum desirability of 0.878 was obtained. 37 Furthermore, the microstructure, surface topography and the distribution quality of cellulose 38 nanofiber in the biopolymer matrix were evaluated by scanning electron microscopy (FE-SEM), 39 atomic force microscopy (AFM) and X ray diffraction (XRD) analysis. |
