The synthesis of biocompatible silver-organic porous films through coordination driven self-assembly.

• A scalable bio-inspired porous silver-based phytic acid films were created. • The phytic acid was utilized as a biotemplate to guide the nucleation and growth of the silver NPs. • The silver-based phytic acid porous films exhibit high chemical and thermal stability. Porous materials have attracted considerable attention in the fields of energy science and environmental applications. However, it remains a great challenge to achieve scalable bioinspired materials with high durability and chemical stability in a porous framework system. This study reports the synthesis of the first silver-based phytic acid films using phytic acid (PA) as an efficient biotemplate without the need of post-modifications or complex reaction conditions. It is found that the hydroxyl groups of PA played a crucial role in initiating and facilitating the growth of silver NPs and formation of a highly stable porous silver film. The present work shed new light on the use of PA for design and synthesis of porous silver-organic bioinspired films. [ABSTRACT FROM AUTHOR]
