摘要：

A regrown composite fiber was synthesized during the sintering of diamond under high pressure 5.8 GPa and high temperature 1500°C for 1 min by using 3% MWCNTs as additive. The experiment results revealed that the outer layer of the fiber is composed of nano-polycrystalline diamond, while the inner fiber is composed of MWCNTs. It is proposed that the untransformed MWCNTs may act as a template for the regrown outer layer of nano-polycrystalline diamond fiber under high pressure and high temperature.
