Abstract: This study is an investigation into the physical and mechanical properties of carbonaceous filler based biocomposites. The effect of low loading at 1, 3 and 5 wt% was investigated by using nano sized carbon filler in the form of carbon black in the initial part of the study and a polymeric material of poly(butylene succinate) as the matrix. The addition of the filler increased the mechanical, thermal and electrical properties of the composites as both materials are relatively hydrophobic in nature. The 5 wt% carbon black loading showed the greatest increase in overall properties. For the second section of the study a biobased lignin alternative carbon powder was produced as a substitute to carbon black by temperature and ball milling optimization. The optimized 900 °C carbonized 24 hour ball milled lignin, showing improved surface area and thermal conductance was then tested with the same polymer. The possible applications of the bionanocomposites produced include automotive interior parts, appliances, packaging, and consumer goods.
