Significant research is currently underway to develop environmentally friendly UV-shielding materials. Herein, we have constructed choline citrate (a biobased ionic liquid, IL) stabilized homogeneous gelatin-lignin UV-shielding films with excellent antimicrobial and mechanical properties. The synthesis procedure of the films is
