Understanding MOF-based Flame Retardants: A Comprehensive Review
Metal-organic frameworks (MOFs) have emerged as a promising avenue for flame retardant research since their first introduction in 2017. These materials offer unique physicochemical properties that can be tailored through targeted design, making them versatile for various applications. However, challenges persist in enhancing the flame-retardant efficiency of MOFs and broadening their scope of use. Researchers are delving into innovative methods to address these issues, with a particular focus on coordination bond cleavage for structurally modifying MOFs.
Challenges and Progress in MOF-based Flame Retardants
The effectiveness of MOFs as standalone flame retardants is limited due to factors such as the presence of flammable ligands, low flame-retardant element content, and inefficient utilization of their microporous structure. To overcome these limitations, researchers are exploring post-synthesis strategies like ion exchange, ligand replacement, and acid/base etching. These approaches have expanded the potential applications of MOFs and paved the way for enhancing their flame-retardant properties.
Coordination Bond Cleavage: A Key Strategy for MOF Modification
A significant advancement in the field of flame retardancy involves the use of coordination bond cleavage to tailor the structure of MOFs. This method enables researchers to modify MOFs without disrupting their fundamental chemistry, leading to the development of efficient flame retardants. By strategically breaking coordination bonds, researchers can enhance the flame-retardant performance of MOFs and explore new avenues for functionalization in polymer nanocomposites.

Metal–organic frameworks (MOFs) are a class of porous polymers consisting of metal clusters (also known as SBUs) coordinated to organic ligands to form one-, two-, or three-dimensional structures. The organic ligands included are sometimes referred to as "struts" or "linkers", one example being 1,4-benzenedicarboxylic acid (BDC). More formally, a metal–organic...
