The Study of Thermal and Morphological Behavior of Hybrid Composite Polyropylene/Wood Flour/Montmorillonite

In this study, the thermal and morphological behavior of polyropylene/wood flour/montmorillonite hybrid composite was investigated. For this purpose, wood flour were mixed with polypropylene at a weight ratio of %40 to %60, and montmorillonite with 0, 2, 4 and 6 phc respectivly, 2 phc of MAPP was also used as a coupling agent in all formulations. Then samples were molded through injection, and thermal properties such as melting tempreature, crystaline temperature and crystalinity point were tested with TGA and DSC techniques. Morphological behavior of the obtained nanocomposite was evaluated by X-ray diffraction. Results indicated that Char melting tempreature, crystaline temperature and crystalinity point were increased with the increase of montmorillonite (modified clay) content; and improved their thermal stability. In addition, the morphological study of the samples showed that montmorillonite particles distributed as intercalation structure in polymer matrix, and the d-spacing of layers were decreased with the increase of modified clay content.
