The bio- and thermal degradation as well as the water absorption properties of a novel biocomposite comprising cellulose nanoparticles, natural rubber and polylactic acid have been investigated. The biodegradation process was studied through an assembled condition based on the soil collected from the central Malaysian palm oil forests located in the University of Nottingham Malaysia. The effects of the presence of the cellulose nanoparticles and natural rubber on the biodegradation of polylactic acid were investigated. The biodegradation process was studied via thermal gravimetric analysis and scanning electron microscopy. It was understood that the reinforcement of polylactic acid with cellulose nanoparticles and natural rubber increases the thermal stability by ~ 20 °C. Limited amorphous regions on the surface of the cellulose nanoparticles accelerated the biodegradation and water absorption processes. Based on the obtained results, it is predicted that complete biodegradation of the synthesised biocomposites can take place in 3062 h, highlighting promising agricultural applications for this biocomposite.
研究了一种由纤维素纳米粒子、天然橡胶和聚乳酸组成的新型生物复合材料的生物和热降解以及吸水性。通过在诺丁汉大学马来西亚分校马来西亚中部油棕林采集的土壤基础上组装的条件，研究了生物降解过程。研究了纤维素纳米粒子和天然橡胶的存在对聚乳酸生物降解的影响。通过热重分析和扫描电子显微镜研究了生物降解过程。结果表明，用纤维素纳米粒子和天然橡胶增强聚乳酸可将热稳定性提高约 20°C。纤维素纳米粒子表面有限的非晶区加速了生物降解和吸水性过程。根据获得的结果，可以预测合成的生物复合材料可以在 3062 小时内完全生物降解，这为这种生物复合材料在农业领域的应用提供了广阔的前景。
