Effect of nano-hydroxyapatite (n-HAp)/PLA scaffold composites on porosity and microstructure
Nowadays, bone tissue engineering is developed rapidly along with better and faster healing needs. One application of bone tissue engineering is improvement in defects. This improvement was completed by regenerating the tissue through a skeleton called scaffold. In this study, nano-Hydroxyapatite (n...

| Summary: | Nowadays, bone tissue engineering is developed rapidly along with better and faster healing needs. One application of bone tissue engineering is improvement in defects. This improvement was completed by regenerating the tissue through a skeleton called scaffold. In this study, nano-Hydroxyapatite (n-HAp)/PLA scaffold composites were successfully made with variations in composition. The basic ingredients for making n-HAp are from natural materials using the sonication method. Addition of PLA into the nHAp matrix was carried out with variations of 10, 20, 30, 40 and 50 wt%. Nano-HAp was characterized using XRD and SEM. n-HAp/PLA composites were characterized by SEM and porosity tests were carried out. The results showed the crystal size of HAp was 14.46nm. The most optimal porosity test on composites with the composition of n-HAp: PLA; 90:10 wt%. |
