No real improvements of tensile strength were observed with the addition of CNF, and the elongation at the break for the CNF composites decreased with increasing reinforcement content. CNF appeared to be better distributed in the PLA + 5 wt.% CNF. Advantages of the carrier system included the use of wet, high solid CNF suspension in combination
with a conventional melt blending process that has been optimized to produce enhanced PLA-based biodegradable nanocomposites. No pre-drying of the CNF was required for PHB/CNF compounding, which can save process time and money.
