| Abstract |
| Hydroxyapatite (HAp) is biocompatible but limited by brittleness and processing
challenges. In this study, HAp-PEG 6000-MgO composites were developed as
candidates for printable bioceramic inks. Composites with different HAp:PEG ratios
(65:35, 60:40, 50:50, 40:60) and 10-18 wt% MgO were synthesized and evaluated.
X-ray diffraction confirmed HAp as the primary phase, with whitlockite as a secondary
phase resulting from Mg incorporation, while FTIR indicated hydrogen bonding
between PEG and HAp/MgO. Scanning electron microscopy showed that MgO reduced
pore size and improved densification. Hardness values of 5-6 on the Mohs scale
place the composites within the range of enamel. The best-performing formulation
was obtained using a HAp:PEG 6000 ratio of 60:40 with 12% MgO and H3PO4
, with
balanced pore size, structural integrity and hardness. Although rheological properties
were not measured, shape and dispersion tests suggest preliminary suitability for
extrusion-based processes. These findings highlight the synergistic role of PEG and
MgO in tailoring HAp composites, supporting their potential as bioceramic inks for
bone tissue engineering. |
