Research on functional boards and plastic films based on animal skin and hydroxyapatite

Abstract Nano-Hydroxyapatite precursors with calcium and phosphorus salts (Ca/P = 1.67) were introduced into a three-dimensional collagen network matrix (3DCM) based on goat skin pretreated with glutaraldehyde for in situ growth, and a functional HAG-3DCM board was obtained. After plasticity compression, a transparent protein plastic film was formed. Response surface methodology based on plasticity pressure conditions was used, and the strength, hardness and water resistance of the HAG-3DCM plastic film was significantly improved. This study demonstrates a new approach for the preparation of animal skin materials with new application value.
