Multilayered materials are widely studied due to their special structures and great properties, such as their mechanical ones. In this paper a novel and effective technique, a quadruple-layering approach, was used to fabricate multilayered materials. This approach increases the number of layers rapidly via simple operations. Materials with 4, 16, and 64 layers with alternating layers of polypropylene and nanocomposites were fabricated using this approach, and their film morphology and mechanical properties were studied. The influence of the number of layers on the mechanical properties of the materials and the relationship between the mechanical properties of each material were investigated. The results illustrated that the tensile modulus and strength were enhanced and elongation at the break increased when the layer numbers of the multilayered materials increased. However, this approach has a defect in that as the layer number increases, the layer thickness was not uniform, thus restricting the improvement of properties. This may need to be further studied in future work.
多层材料因其特殊的结构和优异的性能而受到广泛研究，例如其力学性能。本文采用一种新颖有效的四层堆积法来制备多层材料，这种方法通过简单的操作可快速增加层数。采用这种方法制备了具有 4、16 和 64 层的交替聚丙烯层和纳米复合材料层的多层材料，并研究了它们的薄膜形态和力学性能。研究了层数对材料力学性能的影响以及各材料力学性能之间的关系。结果表明，随着多层材料层数的增加，拉伸模量和强度得到提高，断裂伸长率也随之增加。然而，这种方法存在一个缺陷，即随着层数的增加，层厚不均匀，从而限制了性能的提高。这可能需要在未来的工作中进一步研究。
