To be suitable for certain construction and furniture applications, wood must be treated with a flame retardant and impregnating flame retardants into the cellulose lumens of wood is an effective flame retardant method. Phytic acid, the main storage form of phosphorus in various plant tissues, is an inexpensive, and non-toxic biomaterial that shows potential applications as an environmentally friendly bio-based flame retardant. In this study, phytic acid and zinc phytate were used to impregnate delignified wood under vacuum and pressure, which greatly enhanced the flame retardancy and smoke su...
