Inspired by the tessellation of strawberry achenes on skin: Preparation of ZIF-67 derived multifunctional flame retardant through supramolecular assembly of cobalt alginate biopolymer in melamine-containing polyphosphazene skeleton

• A preparation strategy of MOF derivatives inspired by strawberry skin morphology. • Biopolymers are tessellated in the skeleton of polyphosphazene by supramolecular assembly . • The single-layer hollow nano hybrid is integrated with multiple flame retardant elements. • The flame retardancy of epoxy resin composites is significantly improved after the introduction of CoA/PZM due to its unique components and nanostructure . The preparation of derivatives using metal–organic framework (MOF) as template is often accompanied by the loss of pore structure. Inspired by the distribution of strawberry achenes on skin, restriction sites based on biopolymers were introduced to reduce the loss of mesoporous structure.…
