چکیده انگلیسی
Low dielectric property of polypropylene (PP) is the main barrier to microwave sintering of PP. In this study, 1 wt% of multi-walled carbon nanotubes (MWCNTs) were incorporated into the PP as the microwave susceptors, together with different amounts (0, 5, 15, and 30 wt%) of hydroxyapatite (HA) to produce PP/MWCNT/HA biocomposites for bone tissue engineering by microwave sintering. A reduction of fabrication time (within 1 min) was achieved and the sintering time decreased with an increase of the HA content. The existence and homogeneous distribution of the HA in the sintered composites were confirmed by X-ray diffraction and back scattered scanning electron microscopy, respectively. Microstructures of these composites were examined and thermal analyses were carried out. The microwave sintering technique developed in this study can be used as an alternative to conventional polymer processing methods for fabrication of microwave transparent PP based composites.
