Abstrak

Gelatin-based bio-nanocomposite films reinforced with carbon dots were developed and characterized to evaluate their mechanical, thermal, and optical properties. The films were prepared with carbon dot concentrations of 0.0, 0.1, 0.5, and 1.0% (w/w) to examine the effect of nanofiller incorporation. Optical analysis showed enhanced ultraviolet–visible absorption at 339–344 nm and red-shifted fluorescence emission at 500–517 nm under 400 nm excitation, indicating improved light-responsive behavior. The addition of carbon dots significantly improved tensile strength, elongation at break, and Young’s modulus, demonstrating enhanced flexibility and mechanical performance. Furthermore, carbon dots reduced the water vapor transmission rate and transparency while increasing film density, indicating improved barrier properties. The film containing 0.5% carbon dots showed the most balanced performance, with a tensile strength of 27.43 ± 0.71 MPa, elongation at break of 23.17 ± 1.66%, and Young’s modulus of 0.26 ± 0.03 GPa. Structural analysis confirmed no significant changes in chemical composition and showed uniform dispersion of carbon dots. Thermal analysis indicated improved stability with a melting temperature of 167°C. These findings highlight the potential of gelatin-based bio-nanocomposite films for sustainable packaging applications.
