Resumo: | The present study considered the effect of nanosilica levels on the thermal, flammability, and morphological properties of nanocomposites made of wood flour and recycled polystyrene. To do so, the recycled polystyrene, wood flour, nanosilica, and maleic anhydride, grafted with polypropylene at a constant level of 3%, were mixed by a twin-screw extruder; then standard experimental samples were made using a hand pressing method. Next, the thermal and flammability properties were measured. The results showed that enhancement of nanosilica content to 6% by weight increased thermogravimetric analysis (TGA) of nanocomposites and more char amount remained; in addition, the limited oxygen index increased. Moreover, scanning electron microscopy (SEM) indicated that an enhancement of nanosilica increased compatibility so that better link and adherence was observed among the fiber and matrix material. |
