Abstract: Nanocomposite films were prepared by the solution casting method by introducing chitin nanofiber (CF) into gelatin (GA)/chitosan (CS) matrix. Several methods were used to characterize the prepared films including FE-SEM, TEM and UV-Vis. SEM images showed that CF could be well dispersed in GA/CS matrix at low loading, while higher CF loadings resulted in the aggregation of particles in the nanocomposites. The addition of CF caused remarkable increase in tensile strength (TS), which leads to improved tensile properties compared with the neat GA/CS film, but decreased elongation at break. In addition, water-resistance of films were enhanced by the CF. Furthermore, the introduction of CF barely affected light transmittance of the obtained nanocompo-site films in the range of visible light regions.
