ENHANCED FLAME RETARDANCY AND MECHANICAL PROPERTIES BY CARBON NANOTUBE AND FUMED SILICA FOR POLYETHYLENE NANOCOMPOSITE
Linear low density polyethylene (LLDPE) nanocomposite with improved flame retardancy and mechanical properties is prepared by incorporation of carbon nanotube (CNT) and fumed SiO2.With the incorporation of 3 wt % SiO2 and 5 wt % CNT, the peak value of heat release rate is significantly decreased by 76%.The improved flame retardancy of LLDPE is due to the formation of a dense and compact char, and the accelerated oxidation crosslinking reaction of LLDPE radicals.More importantly, although both SiO2 and CNT are used without pretreatments, LLDPE nanocomposites incorporating both nanofillers show much higher mechanical properties compared to those of neat LLDPE, which is ascribed to good dispersions of nanofillers and strong matrix-nanofiller interfacial interactions.
