| Abstract Scope |
The present study focuses on improving the flexibility of PLA by reinforcing it with a nano-hydroxyapatite (n-HAp) filler. The n-HAp was synthesized from pyrolysis of pink perch fish scales (PPFS) and was characterized using XRD, FTIR, Raman spectroscopy, TGA, SEM, and TEM. n-Hap of 0.25, 0.5, 0.75, and 1 wt.% was used to reinforce the PLA matrix, and PLA/HAp composite blown films were extruded for further studies. The PLA/HAp composite blown films were characterized using XRD, FTIR, Raman spectroscopy, and SEM to understand the interaction of the n-HAP in the PLA matrix. The thermal and mechanical analysis of the PLA/HAp blown films reveals that a low concentration of n-HAp can reduce the thermal stability and improve the flexibility of the films. Tensile results show that PLA_HAp 0.5 exhibited maximum flexibility with elongation at break 20%. |
