Abstract

Nanoaluminum tetraborate (Al2(B4O7)3) and nanoaluminum tungstate (Al2(WO3)3) were prepared by in situ precipitation method on the surface of cellulosic fibers to achieve flame retardant nanocomposite fibers. The prepared nanocomposite fibers were characterized by several techniques such as XRD, SEM, TEM, EDS, and FTIR. Al2(B4O7)3 and Al2(WO3)3 with less than 100 nm in size were dispersed throughout on the surface of the fibers without the formation of large aggregates which showed effective flame retardancy properties. It was found that loading 2. 60% Al2(B4O7)3 and 4. 95% Al2(WO3)3 onto the cellulosic fibers improved greatly the ﬂ ame retardancy behavior of nanocomposite fibers which was approved by vertical flame test and limiting oxygen index (LOI) values. The thermal stability and amount of heat release of untreated and ﬂ ame retardant fibers were evaluated by thermogravimetric (TGA) and differential scanning calorimetry (DSC) analyses. The results showed that the ﬂ ame retardancy mechanism of the obtained flame retardant nanocomposite fibers probably is a condensed-phase phenomenon due to the formation of a protective char layer that acts as a mass transport barrier and a thermal insulator.
