Improvement in mechanical property and bioactivity of PEEK/HA/CF nanocomposite using solid-state processing method |
| 초록 |
Carbon fiber reinforced polyetheretherketone (CFRPEEK) has adjustable mechanical properties similar to cortical bone and is employed as one of the most potential candidates for replacing surgical metallic implants. However, the bioinertness of CFRPEEK limit its implant application. Herein, we show a simple and effective method to prepare CFRPEEK–hydroxyapatite (HA) composites with improved mechanical properties and bioactivity. In the solid-state processing, the chamber with the rotor applies strong shear, compression and friction force to the mixed materials, leading to good dispersion of fillers. The resulting nanocomposites exhibited improved mechanical properties and bioactivity. In particular, the degradation in flexural strength at high HA content was prevented, which showed superior results compared to the control in in vitro cell-compatibility test. Therefore, this process can produce polymer composites with improved functionalities, greatly extending implant applications. |
