Abstract:
Biocomposite has received much attention in recent years as an alternative way to substitute petroleum-based plastic materials. Poly(lactic acid) (PLA) is one of the promising biodegradable polymers due to its excellent mechanical properties, easy processability, and potential industrial production. Mixing with natural fiber such as sawdust, a waste from the wood industry, reduces the product cost. However, natural fiber is hydrophilic whereas the polymer matrix is hydrophobic. To improve the miscibility between PLA and sawdust, sawdust was treated by sodium hydroxide and coupling agents. Hydrophobicity of sawdust increased after treatment. PLA was compounded with treated sawdust by using a twin-screw extruder, then the biocomposite specimens were prepared by using a compression molding machine. Thermal stability of the prepared biocomposite was determined by thermogravimetric technique. Degradation behavior of the biocomposite was mainly affected by the treated sawdust. Mechanical strength was investigated by a universal testing machine. Impact strength and hardness of the biocomposite were also measured. Compared to PLA, a flexural modulus of the biocomposite was increased. Moreover, the addition of the treated sawdust affected on impact strength and hardness
