| description | The invention relates to the technical field of biomaterials, in particular to degradable polyurethane foam and an application thereof. A preparation process of the degradable polyurethane foam is simple, shorter in cycle and capable of preventing introduction of impurities; an obtained product has better water absorption property and higher porosity, can be degraded rapidly and is suitable for clinical application. The polyurethane foam is prepared from polyurethane through dissolving in an organic solvent and freeze-drying, wherein polyurethane is prepared from oligomer polyol as a soft segment and polyisocyanates as a hard segment and a chain extender with an ontology one-step process, and the oligomer polyol is a mixture of hydrophilic polyol and degradable polyol. The degradable polyurethane foam in an embodiment of the invention is used for preparing hemostatic materials, wound dressing or ear and nose stuffing.
