研究了纳米粘土和发泡条件对微孔高密度聚乙烯（HDPE）-粘土纳米复合泡沫材料的泡沫形态和力学性能的影响。0.5、1.0和2.0重量%的粘土负载并通过间歇发泡工艺使用CO2制备微孔HDPE-粘土纳米复合泡沫。单轴拉伸试验与纳米复合材料及其泡沫进行。结果表明，适当的粘土含量，纳米粘土在HDPE中具有改善力学性能的作用，如弹性模量和拉伸强度。另外，HDPE-粘土泡沫的拉伸性能相比于纯HDPE泡沫得到增强。在纳米复合材料和纳米复合材料泡沫的情况下，在0.5wt.粘土加载量。
The effects of nanoclay and foaming conditions on the foam morphology and mechanical properties of microcellular high density polyethylene (HDPE)–clay nanocomposite foams are investigated. Clay loadings of 0.5, 1.0, and 2.0 wt.% are used and the microcellular HDPE–clay nanocomposite foams are prepared by batch foaming process using CO2. Uniaxial tensile tests are performed with the nanocomposites and its foams. It is demonstrated that nanoclays in HDPE, with proper clay contents, have a role to improve the mechanical properties, such as elastic modulus and tensile strength. In addition, tensile properties of HDPE–clay foams are reinforced when compared to that of pure HDPE foams. In the case of both nanocomposites and nanocomposite foams, the mechanical properties are improved most at 0.5 wt.% clay loadings.
