The strong demand for plastic and polymeric materials continues to grow year after year, making these industries critical to address sustainability. By functioning as a filler in either a synthetic or natural starch matrix, nanoclay enables significant reductions in the impact of nonbiodegradable materials. The effect of treated nanoclay (NC) loading on the mechanical and morphological properties (EP) of epoxy is investigated in this research. The NC-EP nanocomposites were prepared via casting. The investigation begins with adding NC at concentrations of 1, 2, and 3 weight percent, followed by the effect of acid treatment on the same nanocomposites. The evaluation is focused on four mechanical tensile strength parameters: Young's modulus, maximum load, and % elongation. The addition of NC improved the mechanical properties of the four components by 27.2%, 33.38%, 46.98%, and 43.58%, respectively. The acid treatment improved 35.9%, 42.8%, 51.1%, and 83.5%, respectively. These improvements were attributed to NC's ability to alter the structural morphology as assessed by field emission scanning electron microscopy (FESEM), a tool for analysing the microstructure. FESEM images were used to visualise the interaction between the NC and EP nanocomposites. The dynamic mechanical properties of the hybrid nanocomposites were investigated using storage modulus, loss modulus, and tan(delta). The results have shown that the viscoelastic properties improved as the fraction of NC increased. The overall findings suggest that these nanocomposites could be used in various industrial and biomedical applications.
对塑料和聚合材料的强劲需求年复一年持续增长,这使得这些行业对于实现可持续发展至关重要。通过在合成或天然淀粉基质中充当填料,纳米粘土能够显著降低不可生物降解材料的影响。本研究考察了经处理的纳米粘土(NC)负载量对环氧树脂机械性能和形态性能(EP)的影响。NC-EP纳米复合材料通过浇铸制备。研究首先添加浓度为1%、2%和3%的NC,然后考察酸处理对相同纳米复合材料的影响。评估集中在四个机械拉伸强度参数上:杨氏模量、最大载荷和伸长率。添加NC分别使四个组分的机械性能提高了27.2%、33.38%、46.98%和43.58%。酸处理分别提高了35.9%、42.8%、51.1%和83.5%。这些改进归因于NC改变结构形态的能力,这通过场发射扫描电子显微镜(FESEM)评估,FESEM是一种用于分析微观结构的工具。FESEM图像用于可视化NC与EP纳米复合材料之间的相互作用。使用储能模量、损耗模量和tan(delta)研究了杂化纳米复合材料的动态力学性能。结果表明,随着NC比例的增加,粘弹性性能得到改善。总体研究结果表明,这些纳米复合材料可用于各种工业和生物医学应用。
