Studies on environmentally-friendly flame retardants for cellulose-based materials
Phytic acid is a naturally occurring compound found in the foods we eat, e.g. in nuts and cereals. It is the most important storage of phosphorus in plants, and phytic acid contains 28% phosphorus.
Phosphorous compounds have proven to be effective flame retardants for cellulose-based materials such as wood and cotton, so phytic acid has the potential to be a non-toxic and environmentally friendly alternative to the flame retardants used today, which in many cases are hazardous to the environment and health. By mixing phytic acid with various common metal ions which are important nutrients for the body, the flame retarding properties can be modified. In this project, chemical theories and analytical methods are used to systematically describe and evaluate the flame retarding properties of different phytic acid-based compounds at the molecular level. The materials to be studied are cotton and wood. The pure phytic acid compounds are studied as reference materials.
