摘要

本研究的目的是通过添加不同重量分数百分比（0，1，1.5，2，2.5，3）%的氧化锆纳米颗粒来改善聚甲基丙烯酸甲酯（PMMA）的机械和热性能。利用浇铸技术制备了（PMMA/氧化锆）纳米复合材料。研究了（PMMA/氧化锆）纳米复合材料的热性能和力学性能。（PMMA/氧化锆）纳米复合材料中氧化锆百分比的增加导致热导率（K）、玻璃化转变温度、比热容（Cp）、渗出性、冲击强度、硬度、弯曲强度、压缩强度和磨损率的增加，从而提高了聚甲基丙烯酸甲酯（PMMA）的热性能和机械性能。

Effect of zirconia addition on thermal and mechanical properties of poly-methyl methacrylate composites

The goal of this study was to improve the mechanical and thermal properties of PolyMethyl Meth Acrylate (PMMA) by adding Zirconia nanoparticles in various weight fraction percentages (0, 1, 1.5, 2, 2.5, 3)%. The cast technique was utilized of to prepare the (PMMA/zirconia) nanocomposites. The thermal and mechanical characterized of (PMMA/zirconia) nanocomposites were studied. Increased zirconia percentages in (PMMA/zirconia) nanocomposites lead to increase thermal conductivity (K), glass transition temperature, specific heat capacity (Cp), effusivity, impact strength, hardness, flexural strength, compressive strength and reduced wear rate, enhancing the thermal and mechanical properties of Poly-Methyl Meth Acrylate (PMMA).
