In the last few decades, there has been an increasing demand for low-cost raw materials and environmentally eco-friendly end products. This demand stimulated a growing interest in natural particles as potential reinforcement materials for composite manufacturing. In this paper, we introduce organic date-seed nanofillers (DSN) as reinforcement materials for the development of enhanced polymer nanocomposites. We particularly investigate the effect of these nanoparticles on two types of polymer base materials, namely medium-density polyethylene (MDPE) and polyethylene terephthalate (PET). A collection of MDPE and PET nanocomposite samples with DSN content ranging from 0.0–0.75 wt% has been prepared using a hot compression method. The MDPE-DSN and PET-DSN nanocomposite structures were analyzed using a scanning electron microscope (SEM), energy-dispersive X-ray analysis (EDXA), and Fourier-transformed infrared spectroscopy (FTIR). The mechanical characteristics of these nanocomposites were experimentally examined through wear loss and Vickers micro-hardness tests. The experimental results show that the MDPE-DSN composite is chemically more stable than the PET-DSN one. Moreover, the MDPE-DSN nanocomposite shows enhanced hardness and wear resistance properties, while the PET-DSN one shows less noticeable enhancements. The best enhancements were obtained with a DSN reinforcement of 0.75 wt%., and a normal load of 10 N. As well, the experimental outcomes show a good agreement with theoretical predictions. In general, the DSN material enhances the mechanical properties of polymer materials and reduces their economic costs.

使用多层析因设计比较纳米枣种子作为中密度聚乙烯(MDPE)和聚对苯二甲酸乙二醇酯(PET)的增强材料的效果

在过去的几十年中,对低成本原材料和环保终端产品的需求不断增长。这种需求激发了人们对天然颗粒作为复合材料生产的潜在增强材料的兴趣。在本文中,我们介绍了有机枣籽纳米填料(DSN)作为增强材料,用于开发增强型聚合物纳米复合材料。我们特别研究了这些纳米粒子对两种类型的聚合物基础材料,即中密度聚乙烯(MDPE)和聚对苯二甲酸乙二醇酯(PET)的影响。使用热压法制备了DSN含量为0.0-0.75 wt%的MDPE和PET纳米复合材料样品。使用扫描电子显微镜(SEM)分析MDPE-DSN和PET-DSN纳米复合材料的结构,能量色散X射线分析(EDXA)和傅立叶变换红外光谱(FTIR)。这些纳米复合材料的机械特性通过磨损损失和维氏显微硬度测试进行了实验检查。实验结果表明,MDPE-DSN复合材料在化学上比PET-DSN复合材料更稳定。此外,MDPE-DSN纳米复合材料显示出增强的硬度和耐磨性,而PET-DSN则显示出不太明显的增强。用0.75 wt%的DSN增强材料和10 N的正常载荷可获得最佳增强效果。实验结果也与理论预测吻合良好。通常,DSN材料增强了聚合物材料的机械性能并降低了其经济成本。和傅立叶变换红外光谱(FTIR)。这些纳米复合材料的机械特性通过磨损损失和维氏显微硬度测试进行了实验检查。实验结果表明,MDPE-DSN复合材料在化学上比PET-DSN复合材料更稳定。此外,MDPE-DSN纳米复合材料显示出增强的硬度和耐磨性,而PET-DSN则显示出不太明显的增强。用0.75 wt%的DSN增强材料和10 N的正常载荷可获得最佳增强效果。实验结果也与理论预测吻合良好。通常,DSN材料增强了聚合物材料的机械性能并降低了其经济成本。和傅立叶变换红外光谱(FTIR)。这些纳米复合材料的机械特性通过磨损损失和维氏显微硬度测试进行了实验检查。实验结果表明,MDPE-DSN复合材料在化学上比PET-DSN复合材料更稳定。此外,MDPE-DSN纳米复合材料显示出增强的硬度和耐磨性,而PET-DSN则显示出不太明显的增强。用0.75 wt%的DSN增强材料和10 N的正常载荷可获得最佳增强效果。实验结果也与理论预测吻合良好。通常,DSN材料增强了聚合物材料的机械性能并降低了其经济成本。这些纳米复合材料的机械特性通过磨损损失和维氏显微硬度测试进行了实验检查。实验结果表明,MDPE-DSN复合材料在化学上比PET-DSN复合材料更稳定。此外,MDPE-DSN纳米复合材料显示出增强的硬度和耐磨性,而PET-DSN则显示出不太明显的增强。用0.75 wt%的DSN增强材料和10 N的正常载荷可获得最佳增强效果。实验结果也与理论预测吻合良好。通常,DSN材料增强了聚合物材料的机械性能并降低了其经济成本。这些纳米复合材料的机械特性通过磨损损失和维氏显微硬度测试进行了实验检查。实验结果表明,MDPE-DSN复合材料在化学上比PET-DSN复合材料更稳定。此外,MDPE-DSN纳米复合材料显示出增强的硬度和耐磨性,而PET-DSN则显示出不太明显的增强。用0.75 wt%的DSN增强材料和10 N的正常载荷可获得最佳增强效果。实验结果也与理论预测吻合良好。通常,DSN材料增强了聚合物材料的机械性能并降低了其经济成本。此外,MDPE-DSN纳米复合材料显示出增强的硬度和耐磨性,而PET-DSN则显示出不太明显的增强。用0.75 wt%的DSN增强材料和10 N的正常载荷可获得最佳增强效果。实验结果也与理论预测吻合良好。通常,DSN材料增强了聚合物材料的机械性能并降低了其经济成本。此外,MDPE-DSN纳米复合材料显示出增强的硬度和耐磨性,而PET-DSN则显示出不太明显的增强。用0.75 wt%的DSN增强材料和10 N的正常载荷可获得最佳增强效果。实验结果也与理论预测吻合良好。通常,DSN材料增强了聚合物材料的机械性能并降低了其经济成本。
