摘　　要：水性聚氨酯是一种亲水聚氨酯分子,在涂料、表面处理、胶黏剂等方面有着广泛应用,但由于水性聚氨酯高亲水性,进而限制了其进一步开发应用。综述了水性聚氨酯概况,分别介绍了无机纳米材料、天然高分子纳米材料和金属氧化物纳米材料改性水性聚氨酯的研究近况,阐述了这几种纳米材料在力学性能、热稳定性、耐水性以及其他特殊性能方面对水性聚氨酯的影响,最后展望了纳米材料改性水性聚氨酯复合材料的发展前景。Waterborne polyurethane is a hydrophilic polyurethane molecule, which has been widely used in coating, surface treatment and adhesive. It is limited for further development and application due to its high hydrophilicity of waterborne polyurethane. The present researches of waterborne polyurethane modified by inorganic nanomaterials, natural polymer nanomaterials and metal oxide nanomaterials were introduced respectively. The modification effects of these kinds of nanomaterials on the mechanical properties, thermostablitity, water resistance and other special properties of waterborne polyurethane were reviewed. The development of the nanomaterials/water polyurethane composites was prospected.
