摘要

本研究主要研究了以腰果酚油和纳米二氧化硅为原料,优化PLA/PCL聚己内酯/聚乳酸生物复合膜的配方。所使用的材料包括PLA颗粒(Mw = 207,000 g/mol)和PCL聚合物(Mn = 95 kDa)。以腰果酚油为增容补强剂。在L9正交设计的基础上,采用不同浓度的PCL(8、10、12 wt.%)、腰果酚油(5、10、15 wt.%)和纳米二氧化硅(1、3、5 wt.%),采用压膜法制备复合薄膜。制备的薄膜厚度从85到100微米不等,在50%的相对湿度和25°C条件下稳定其性能。结果表明,A2B1C3 (10 wt.% PCL, 5 wt.%腰果酚油,5 wt.%纳米二氧化硅)的最佳工艺参数组合显著提高了材料的力学性能,拉伸强度为91.47 MPa,疏水性为95.25°,灰色关联度(GRG)提高了2.57%。这些结果强调了使用腰果酚油和纳米二氧化硅来改善PLA/PCL共混物的相容性和性能的有效性,为开发用于包装应用的可持续生物复合薄膜提供了有价值的见解。FTIR分析表明PLA/PCL与添加的组分之间具有有效的相容性,在2900 cm - 1和3300 cm - 1处有不同的峰,分别表示CH烷基键和OH酚基团。SEM图像的形态分析证实了纳米二氧化硅和腰果酚油在PLA/PCL基体中的均匀分布,这增强了复合材料的性能,尽管观察到微小的亚微米间隙和凹坑。与以前的研究不同,这项研究没有探索这些添加剂的理想量或综合效果。这项工作采用了系统的方法,使用田口L9正交阵列来确定最佳的输入工艺参数。然而,本研究存在一定的局限性,如大规模生产生物二氧化硅对原料的要求,并且本研究对有限的性能进行了优化研究。这可以通过即将在此背景下进行的研究以及对该研究进行更多的性质研究来克服。此外,天然材料影响的生物膜复合材料在食品包装工业、制药、生物医学等领域具有潜在的应用前景。

Optimization of tensile and water absorption properties of biosilica dispersed cardanol oil blended PLA/PCL biocomposite for packaging applications

The present research study focuses on optimizing the formulation of (PLA/PCL) polycaprolactone/polylactic acid biocomposite films for durable packaging applications by incorporating cardanol oil and nanosilica. The materials used include PLA pellets (Mw = 207,000 g/mol) and PCL polymer (Mn = 95 kDa). Cardanol oil were utilized as compatibilization and reinforcing agents. Composite films were prepared using a film casting method with varying concentrations of PCL (8, 10, 12 wt.%), cardanol oil (5, 10, 15 wt.%), and nanosilica (1, 3, 5 wt.%) based on the L9 orthogonal design. The produced films, with thicknesses ranging from 85 to 100 microns, were conditioned at 50% relative humidity and 25 °C to stabilize their properties. The key findings reveal that the optimal combination of process parameters, A2B1C3 (10 wt.% PCL, 5 wt.% cardanol oil, and 5 wt.% nanosilica), significantly enhanced the mechanical properties, achieving a tensile strength of 91.47 MPa and hydrophobicity of 95.25°, showing a 2.57% improvement in Grey Relational Grade (GRG). These results underscore the effectiveness of using cardanol oil and nanosilica to improve the compatibility and performance of PLA/PCL blends, providing valuable insights for developing sustainable biocomposite films for packaging applications. The FTIR analysis demonstrated effective compatibility between PLA/PCL and the added components, with distinctive peaks at 2900 cm⁻1 and 3300 cm⁻1 indicating CH alkyl bonds and OH phenolic groups, respectively. Morphological analysis using SEM images confirmed a uniform distribution of nanosilica and cardanol oil within the PLA/PCL matrix, which enhanced the composite’s properties, although minor submicron gaps and pits were observed. Unlike previous studies, this did not explore the ideal amounts or combined effects of these additives. This work employs a systematic approach using the Taguchi L9 orthogonal array to determine optimal input process parameters. However, this study has certain limitations like requirement of raw material for mass production of biosilica, and limited properties are studied under optimization in this study. This can be overcome by upcoming research study on this background and more properties studies on this research. Moreover, the natural material influenced biofilm composite can potentially be applied in areas such as food packaging industry, pharmaceutical, biomedical field, etc.
