In the present research, titanium dioxide (TiO2) nanoparticles (NPs) were prepared by using sol‐gel technique, and the phase structure and morphology of obtained TiO2 NPs were characterized by using X‐ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. The XRD patterns of the TiO2 NPs indicated the formation of anatase phase. A new nanocomposite film has been developed by solvent casting method from collagen hydrolysate (CH) and TiO2 NPs at different concentrations for use in packaging industry. Fourier transform infrared (FTIR) spectra showed the intermolecular reactions between CH and TiO2 NPs in the films. SEM micrographs revealed a clear dispersion of TiO2 NPs on the surface of the films especially at low concentrations. Thermal analyses showed that after incorporation of TiO2 NPs in polymer matrix, heat susceptibility of films were changed and weight loss of films was decreased. The results revealed that incorporation of TiO2 NPs significantly decremented water vapor permeability (WVP), water solubility, and elongation at break (EAB) of the films, whereas tensile strength (TS) significantly incremented. The findings pointed out that TiO2 NPs can be successfully incorporate to the CH films and the reutilization of CH in nanocomposite films will be a promising alternative material in non‐food packaging industry.

“…In fact, the fibers were immersed in the TiO 2 sol through the grafting process. This led to an impregnation of TiO 2 particles both on the surface and through the lamina [28]. The TiO 2 particles possibly replaced some part of the fiber moisture which led to balance the masses and consequently the densities.…”

“…Among natural and renewable materials, cellulose is one of the promising resources because it can be easily gained and lots of hydroxyl groups on the chain can be functionalized for special applications [24][25][26][27][28][29][30]. Cellulose has been applied in waste water treatment [24][25][26][27], reinforcing composite materials [28], as well as in bio-derived and bio-inspired materials [29,30]. Populus fibers (PF), a kind of natural cellulose, produced from poplar seeds, has been treated as waste or used as a cheap fertilizer because the fibers are soft and short, with low intensity and longitudinal torsion [31].…”

The surface modification of natural materials to be applied in removal of Cr (VI) from aqueous solutions has attracted much attention. A natural sorbent for Cr (VI) based on natural populus fibers (PF) is prepared by transforming the cyano groups (AN) in polyacrylonitriles (PAN) grafted from PF into amidoxime groups (AO), which has strong ability to attract and chelate heavy metal ions. The prepared sorbent is characterized by Fourier Transform Infrared Spectra (FT-IR), thermogravimetric analysis (TGA), solid-state nuclear magnetic resonance ( 13 C-NMR) and scanning electron microscope (SEM). As potassium dichromate solution (K 2 Cr 2 O 7 ) is used as a target solution for detecting adsorption capacity of the sorbent, the adsorption kinetics of the sorbent for chromiun is consistent with the pseudo-second-order kinetic model by analyzing the adsorption amount as a function of the sorbent dispersed duration in solution at pH = 2. The expected adsorption mechanism is that the Cr (VI) in anionic ions Cr 2 O 7 2and HCrO 4 are adsorbed through electrostatic attraction but when Cr (VI) is reduced to Cr (Ⅲ) by AO, the electronegative nitrogen and oxygen in AO chelate it through coordination bond. The as-prepared PF derivant with high adsorption efficiency of chromium 180.5 mg/g (3.47 mmol/g), low cost, reusability and greenly preparation process suggests that the development of natural PF as a sorbent in removal of Cr (VI) from aqueous solutions is a destined significant approach.
