Abstract: Sodium alginate/nanomaterial composites are blends of sodium alginate and nanomaterial fabricated by certain technology. Recently，more interest has been attracted to those composites. It is mainly due to their excellent physicochemical properties，functional features，good biocompatibility and special nanometer effect. In this paper，the physicochemical properties and functional features of sodium alginate/nanomaterial composites were introduced，and their application in pharmaceutical，food and industry were summarized，including the research and progress in drug delivery，tissue engineering scaffold，antibacterial material，wound dressing，food packaging，industrial production and sewage treatment. The application of sodium alginate/nanomaterial composites would be promising，but in order to facilitate the commercial adoption，certain problems also need to be solved，such as the optimization of preparation technology，and the evaluation of their safety.
