Physicochemical properties of COL/CS composite films. Histogram comparing the tensile mechanical properties of the COL film, COL/CS film, and COL/3CS film, including (A) elastic modulus, (B) tensile strength, (C) stress–strain curves, and (D) elongation at break. (E) Histogram comparing the water content of COL/CS composite films. (F) The lysozyme-mediated biodegradation of the COL/CS composite films after absorbing water at different times. (G) Images of the water contact angle of films. (H) Quantitative comparative analysis of contact angles of COL/CS composite films. Values represent the mean ± SD, n = 5, *p < 0.05.
