To do so, the recycled polystyrene (50%), wood flour (50%), nanosilica (four levels of nanosilica; 0, 2, 4 and 6 phc (parts per hundred compounds)), and maleic anhydride, grafted with polypropylene (at a constant level of 3 phc) 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 increasing of nanosilica content to 6 phc by weight increased thermogravimetric analysis (TGA) of nanocomposites; in addition, the limited oxygen index increased. Moreover, scanning electron microscopy (SEM) indicated that an increasing of nanosilica increased compatibility so that better link and adherence was observed among the fiber and matrix material. 2018 artículo científico 0104-7760 https://www.redalyc.org/articulo.oa?id=74460165007 https://www.redalyc.org/journal/744/74460165007/ https://www.redalyc.org/journal/744/74460165007/html/ https://www.redalyc.org/journal/744/74460165007/74460165007.epub https://www.redalyc.org/journal/744/74460165007/movil 10.1590/01047760201824012383 en http://www.redalyc.org/revista.oa?id=744 CERNE application/pdf Universidade Federal de Lavras CERNE (Brasil) Num.1 Vol.24 |
