The purpose of this study is to evaluate the rheological and thermal properties of poly(l-lactic acid) (PLA) composites incorporated with microcrystalline cellulose (MCC) and lignin. The MCC/lignin/PLA composites were fabricated through direct melt compounding. In particular, the effect regarding the addition of MCC was analyzed from a rheological perspective. Additionally, the morphological properties of the composite were explored via SEM observation. From the thermal analysis, it revealed that well-dispersed MCC at the nanoscale level increased cold crystallization temperature and that the addition of lignin enhanced the thermal stability of composites.
本研究旨在评估聚乳酸（PLA）复合材料的流变学和热性能，这些复合材料中加入了微晶纤维素（MCC）和木质素。MCC/木质素/PLA 复合材料是通过直接熔融共混制备的。具体而言，从流变学角度分析了添加 MCC 的效果。此外，还通过 SEM 观察研究了复合材料的形态特性。从热分析中可以发现，在纳米尺度上均匀分散的 MCC 提高了冷结晶温度，而添加木质素则提高了复合材料的热稳定性。
