Research Progress on Stimulus-responsive Layer-by-layer Self-assembled Films
Multilayer films with precisely controlled composition,structure and thickness can be constructured via a alternating deposition technique,which was named layer-by-layer self-assembly technology for typical film preparation strategy.A wide range of functional species can be introduced into multilayer films as building blocks or in other ways,which greatly expands the application prospects of multilayer films.Stimulus-responsive layer-by-layer self-assembled films are a new type of polymer films that are responsive to external stimuli,and they can respond to changes in external environmental stimuli and exhibit unique physical and chemical properties.The driving force,stimulus-responsive mode and application fields of layer-by-layer self-assembled films are introduced,the latest research progress of stimulus-responsive layer-by-layer self-assembled films is summarized in recent years,and its future development trend is prospected.
