The present application provides a polyurethane sponge material, a preparation method therefor, a use thereof and a polyurethane sponge article, and relates to the technical field of biological materials. The polyurethane sponge material provided in the present application comprises strontium-boron bioactive glass and polyurethane. The polyurethane sponge material has good bioactivity, biodegradability and biocompatibility, and can be used as a composite artificial skin for wound repair and treatment integration. Furthermore, wound vascularization and skin regeneration can be effectively induced, skin damage can be quickly repaired in situ, adhesion is not easily caused, and secondary trauma is avoided, thereby achieving better effects in facilitating wound repair. The preparation method for the polyurethane sponge material provided in the present application is simple and easy to operate, can conveniently achieve shaping, has low polymerization temperature, and is easy to apply, and the prepared polyurethane sponge material has good bioactivity, biodegradability and biocompatibility. |
