| Research Abstract |
The immobilization of bromine flame retardant and phosphorous flame-retardant was successfully achieved. The limiting oxygen index value of epoxy filled with these flame retardant-immobilized silica was higher than that of epoxy resin filled with untreated silica and free flame retardants. Photostabilizer was also immobilized onto silica surface. The composites filled with the photostabilizer-immobilized silica has an ability to absorb UV light. The elimination of additives from polymer matrices filled with these flame retardant-and photostabilizer-silica into boiling water was hardly observed. The results clearly show the anchor effect of silica nanoparticle for the immobilization of flame retardant and photostabilizer.
