摘要

In this study, chemically treated Alcell lignin was used as a compatibilizer in the preparation of polypropylene-oil palm empty fruit bunch (PP-EFB) composites. Basically, this study was divided into two stages. In the first stage, glycidyl methacrylate (GMA) and allyl glycidyl ether (AGE) were used to treat Alcell lignin in different ratios (1:1, 1:2 and 1:3) based on equivalent weight. Then, the treated lignin was used as a compatibilizer at different percentages (1%, 3% and 5%, based on the weight of EFB filler) in the preparation of lignocellulosic-thermoplastic composites. The size of the EFB filler used for this study was 53-180 um and the ratio of PP to EFB filler was fixed at 40%:60% (based on weight). The results showed that the incorporation of GMA- and AGE-treated lignin had enhanced the mechanical properties and increased the hydrophobicity of lignocellulosic-thermoplastic composites. By comparison, those with the GMA-treated lignin exhibited better enhancement in mechanical properties as compared to those with AGE-treated lignin.
