Nanocellulose,a new bio-based nanomaterial,shows great application potential in many fields due to its excellent mechanical properties,surface chemical modifiability and other characteristics.However,the high flammability of nanocellulose restricts its application to a large extent,therefore improvement on its flame retardancy is of great significance.In this review,the common methods for synthesis of flame-retardant nanocellulose-based materials were firstly introduced,with emphasis on the preparation of intrinsic as well as additive nanocellulose based flame-retardant composite materials.Several main types of flame-retardant nanocellulose-based materials(including film,aerogel,filament,etc.)and their applications were then summarized.Finally,the future development direction of flame retardant modification on nanocellulose was discussed.
