In recent years, the development and use of polymeric nanocomposites in creating advanced materials has expanded exponentially. A substantial amount of research has been done in order to design polymeric nanocomposites in a safe and efficient manner. In the present study, the impact of processing parameters, such as, barrel temperature, and residence time on the mechanical and thermal properties of high density polyethylene (HDPE)-TiO₂ nanocomposites were investigated. Additionally, scanning electron microscopy and X-ray diffraction spectroscopy were used to analyze the dispersion, location, and phase morphology of TiO₂ on the HDPE matrix. Mechanical tests revealed that tensile strength of the fabricated HDPE-TiO₂ nanocomposites ranged between 22.53 and 26.30 MPa, while the Young's modulus showed a consistent increase as the barrel temperature increased from 150 °C to 300 °C. Moreover, the thermal stability decreased as the barrel temperature increased.
近年来，聚合物纳米复合材料在先进材料制造中的开发和应用呈指数级增长。为了以安全有效的方式设计聚合物纳米复合材料，已经开展了大量研究。在本研究中，研究了诸如料筒温度和停留时间等加工参数对高密度聚乙烯（HDPE）-TiO₂纳米复合材料的力学和热性能的影响。此外，使用扫描电子显微镜和X射线衍射光谱分析了TiO₂在HDPE基体上的分散、位置和相形态。力学测试表明，制备的HDPE-TiO₂纳米复合材料的拉伸强度在22.53至26.30MPa之间，而随着料筒温度从150℃升高到300℃，杨氏模量持续增加。此外，热稳定性随着料筒温度的升高而降低。
