Modular design of biomimetic electrospun keratin composites for tunable gaseous sorption inspired by reptile eggshells.

ABSTRACT: Biomimicry, the replication of natural structures, is an emerging strategy in materials engineering for developing advanced functional materials. Reptile eggshells serve as compelling models for tunable bioinspired material design due to their diversity in forms and functions. This study presents a modular approach to designing keratin-based composites with customizable vapor sorption behavior. Inspired by reptile eggshells, four key biomimetic components were reconstructed: (1) electrospun keratin membranes resembling the fibrous shell membrane, (2) an egg protein matrix replicating the proteinaceous eggshell matrix, (3) calcium carbonate (CaCO₃) particles introducing mineralization, and (4) a paraffin coating representing the lipid-rich cuticle layer. The modular accuracy of t
