| A novel bulk multi-wall carbon nanotubes (MWCNTs) sintered with polycarbosilane (PCS)as a binder agent was fabricated by spark plasma sintering(SPS), and their microstructure and properties were investigated. Sintering was done with the pressure in the range of 20'60 MPa at 1200℃. SEM and TEM observations showed that the nano-sized tube microstructure was preserved even after sintering and tubes were adhered to each other with the nano-nodules of SiC pyrolyzed form PCS as revealed by X-ray diffraction.The bulk density and Vickers hardness were increased and the specific surface area was reduced with increasing the content of PCS and sintering pressure.The inflammatory reaction of CNTs/PCS materialistic properties close to bone and good biocompatibility from tissue response would be suitable as a candidate implant dental materials in the future.
