Room Temperature Preparation of Aluminum Hydroxide Nanoparticles and Flame Retardant Poly Vinyl Alcohol Nanocomposite

Al(oh)3  nanoparticles  were  synthesized  by  a  simple  precipitation reaction.  the  effect  of  various  amines  like  ethylene  diamine, propylene  diamine,  triethylenetetramine  and  tetraethylenepentamine as precipitating agents on the morphology of al(oh)3 nanostructures was  investigated.  the  influence  of  al(oh)3  nanoparticles  on  the flame retardancy of the poly vinyl alcohol (pva) matrix was studied using ul-94. nanostructures were characterized by x-ray diffraction (xrd),  scanning  electron microscopy  (sem) and fourier  transform infrared  (ft-ir)  spectroscopy.  flame  retardancy  of  the nanocomposites enhanced in the presence of al(oh)3 nanostructures. this  improvement  of  nanocomposites  is  due  to  the  endothermic decomposition  of  al(oh)3  and  release  of  water  which  dilutes combustible gases.
