Abstract
Short-fiber-reinforced biodegradable polymer films offer a promising pathway toward sustainable materials combining mechanical robustness with added functionality. Here, we present agar-based composite films reinforced with biodegradable short electrospun poly(methyl methacrylate-co-methacrylic acid) fibers, examining the effects of fiber loading on mechanical, optical, and thermal performance. Short fibers were produced via a scalable electrospinning process and incorporated into agar films at 1, 5, and 10 wt.% via one-step casting. All composite films maintained consistent thickness (∼90–93 µm). Relative to neat agar, composites containing 10 wt.% fibers exhibited a 67% increase in tensile strength and a 72% increase in toughness while maintaining ductility, indicating efficient stress transfer enabled by the dispersed short-fiber architecture. Beyond mechanical reinforcement, fiber incorporation imparted pronounced UV-shielding capability, reducing transmittance at 280 nm from 31.6% to 0.57% (>99% UV blocking) and visible-light transmittance at 600 nm from 68.3% to 2.4%, enabling tunable optical control. Thermal analysis and FTIR spectroscopy confirmed fiber integrity and predominantly physical fiber–matrix interactions. These results demonstrate that poly(methyl methacrylate-co-methacrylic acid) electrospun short fibers can function as effective, fully biodegradable reinforcements, enabling scalable production of multifunctional polymer films with enhanced mechanical performance and sustainable UV-protective functionality suitable for food packaging applications.
