Effects of micrometre-sized graphite flake to reinforce the performances of poly (lactic acid) thermoplastic biocomposites

Biocomposites of poly(lactic acid) (PLA) and micrometre-sized graphite (GP) flake powder with 0–30 wt% GP contents have been prepared using extrusion moulding followed by compression moulding. The pure PLA and PLA-GP composites (PGC) have been examined by Fourier transform infrared (FTIR) spectrosco...
