Sustainable 3D Scaffolds Based on β-Chitin and Collagen I for Wound Dressing Applications.

ABSTRACT: The development of greener substitutes for plastics is gaining massive importance in today's society. This also involves the medical field, where disposable materials are used to grant sterility. Here, a novel protocol using only a water-based solvent for the preparation of bio-based composite foams of actual β-chitin and collagen type I is presented. The influence of the ratio of this chitin polymorph to the collagen on the final material is then studied. The samples with 50:50 and 75:25 ratios produce promising results, such as remarkable water absorption (up to 7000 wt.%), exposed surface (up to 7 m²·g^-1), and total pore volume (over 80 vol.%). The materials are also tested using wet mechanical compression, exhibiting a Young's modulus and tenacity (both calculated
