FLAME-RETARDANT AND ANTICORROSIVE SURFACE

] is such a flame retardant, which is commonly used in combination with many polymers. Therefore, in this study, a novel nanocomposite of PANI/Mg(OH) 2 is synthesized starting from naturally occurring dolomite. In this method, powdered dolomite was heated, at 900 °C, for 3 h, to produce calcined dolomite (CaO.MgO).
