This study examines the influence of cellulose nanocrystal (CN) particles on the morphological, thermal, and thermo-mechanical properties of polylactide (PLA)/poly [(butylene succinate)-co-adipate] (PBSA) blend foams prepared by casting and particulate leaching method using fructose as porogen particles. The morphological analysis showed an interconnected open-cell structure, with porosity above 80%. The crystallinity of the prepared foams was disrupted by the inclusion of CN particles as observed from XRD analyses, which showed a decrease in PLA crystal peak intensity. With regards to neat blend foam, the onset thermal degradation increased with the addition of CN particles, which also increased the thermal stability at 50% weight loss. Furthermore, CN acted as a reinforcing agent in improving the stiffness of the prepared blend foam. Overall, completely environmentally friendly foams were successfully prepared, as a potential material that can replace the current existing foam materials that pose many environmental concerns. However, there is a need to develop an environmentally friendly processing technique.

纤维素纳米晶体增强的聚丙交酯/聚[（丁二酸丁二酯）-共己二酸酯]共混复合泡沫塑料的形貌，热学和热力学性能

这项研究调查了纤维素纳米晶体（CN）颗粒对聚丙交酯（PLA）/聚[（丁二酸丁二酯）-共己二酸酯]（PBSA）混合泡沫的形态，热学和热机械性能的影响，这些泡沫是通过铸造和颗粒制备的使用果糖作为致孔剂颗粒的浸出方法。形态学分析显示互连的开孔结构，孔隙率高于80％。从XRD分析中观察到，CN颗粒的加入破坏了制备泡沫的结晶度，这表明PLA晶体峰强度降低。对于纯净的共混泡沫，开始的热降解随着CN颗粒的添加而增加，这也增加了重量减少50％时的热稳定性。此外，CN在改善所制备的共混泡沫的劲度方面用作增强剂。总体，成功制备了完全环保的泡沫材料，作为一种有潜力的材料，可以替代目前引起许多环境问题的现有泡沫材料。然而，需要开发环境友好的加工技术。
