Since the demand for high performance products is ever growing, to combine the characteristics of biomaterials and synthetic polymers through a facile method may stand out as a forerunner to the materials design and application. Herein, waterborne polyurethane/collagen (WPU/CO) composites were prepared by a green facile method. Interactions between collagen and polyurethane segments lead to hybrid domain with high modulus within WPU/CO composites. Such bonding effect making obtained compounding system more tolerant of multiple stretching and external force. Owing to presence of collagen fibrils, WPU/CO coatings exhibited superior temperature-adaptive water vapor permeability and hydrophilicity. Moreover, compares to pure WPU, WPU/CO composite containing 5.4 wt.% collagen showed significantly enhanced self-healing ability with healing efficiency of strain and tensile stress improved by 651% and 86% respectively. These properties are believed to benefit application of WPU/CO composites as comfort functional materials.

由于对高性能产品的需求不断增长，因此通过简便的方法将生物材料和合成聚合物的特性结合起来可能成为材料设计和应用的先驱。在此，通过绿色简便方法制备了水性聚氨酯/胶原蛋白（WPU / CO）复合材料。胶原蛋白和聚氨酯链段之间的相互作用导致WPU / CO复合材料中具有高模量的杂化区域。这样的粘合效果使得获得的复合系统更能承受多重拉伸和外力。由于存在胶原原纤维，WPU / CO涂层显示出优异的温度适应性水蒸气渗透性和亲水性。此外，与纯WPU相比，WPU / CO复合材料的含量为5.4 wt％。％的胶原蛋白显示出显着增强的自愈能力，其中应变的治愈效率和拉伸应力分别提高了651％和86％。据信这些性能有利于将WPU / CO复合材料用作舒适功能材料。
