Abstract :
In this paper, nano-silica with and without surface modification was used to prepare linear low density polyethylene (LLDPE) /silica composites whose thermal stability and combustion behaviors were investigated by thermal gravimetric analysis (TG) and cone calorimeter (CONE), respectively. As a result of TG, composites with surface modified nano-silica possessed better thermal stability than that with pristine nano-silica. The results of CONE proved better combustion properties of composites with surface modified nano-silica by showing reduced heat release rate (HRR) and mass loss rate (MLR).
