Abstract: Research progress of waterborne polyurethane modified by nanomaterials,such as natural polymer nanomaterials,clay and mineral nanomaterials,carbon nanomaterials,metal and metal oxide nanomaterials is summarized. Compatibility between nanomaterials and polymer matrix can be improved by chemical modification,which is beneficial to obtain stable hybrid emulsions. Physical blending modification can endow composites more excellent properties of nanomaterials. Nano-particles uniformly dispersed in waterborne polyurethane matrix can significantly improve thermal stability and mechanical properties of nanocomposites. Efficient and practical organic modification technology of nanomaterials and optimization of production technology of nanocomposites will be the development trend to obtain high performance nanocomposites in the future.

Key words: waterborne polyurethane, nanomaterials, modification, composites, polymers
