The Role of WO₃ Nanoparticles on the Properties of Gelatin Films.

ABSTRACT: Gelatin films are very versatile materials whose properties can be tuned through functionalization with different systems. This work investigates the influence of WO₃ nanoparticles on the swelling, barrier, mechanical, and photochromic properties of gelatin films. To this purpose, polyvinylpirrolidone (PVP)-stabilized WO₃ nanoparticles were loaded on gelatin films at two different pH values, namely, 4 and 7. The values of swelling and solubility of functionalized films displayed a reduction of around 50% in comparison to those of pristine, unloaded films. In agreement, WO₃ nanoparticles provoked a significant decrease in water vapor permeability, whereas the decrease in the values of elastic modulus (from about 2.0 to 0.7 MPa) and stress at break (from abou
