The effect of particle size on the rheological properties of polyamide 6/biochar composites

Abstract

To abeb the potential of biochar as filler for thermoplastic materials and to optimize its procebing conditions, composites of polyamide 6 and biochar were produced by extrusion followed by injection moulding. Biochar was prepared by grinding and ball-milling, respectively before addition to the polymer. The different biochar treatments resulted in strong differences in the mean particle size as well as the particle size distribution. The size of the filler particle significantly influences the flow behaviour of the melt.
