In this research, the comparison of the effect of adding nanoparticles (clay, chitosan, TiO2 and bacterial nanocellulose) separately on the physical, mechanical and optical properties of the film prepared from the lantern fish protein was investigated. To prepare nanocomposite films, nanoparticles were added separately at 1 and 3% levels to the protein film solution extracted from the lantern fish. The results showed that with the addition of nanoparticles in the polymer substrate, the tensile strength of all films showed a significant increase. Elongation at breaking point in films containing nanoparticles of clay, TiO2 and bacterial cellulose increased significantly and the water vapor permeability improved in films containing nanoparticles (clay, cellulose and TiO2). Also, the moisture content of the films increased with the addition of nanoparticles and the solubility values showed a significant increase in the rest of the films containing nanoparticles, except for cellulose nanoparticles. The opacity of the films also increased with the addition of nanoparticles.
