摘要

稻壳被用来制造二氧化硅颗粒，然后用来增强聚合物基体。利用x射线衍射、傅里叶变换红外光谱(FTIR)和扫描电镜能谱仪(EDS)对合成的SiO2颗粒进行了表征。在PMMA基体中，分别以1、3、5 wt.%的SiO2颗粒作为补强剂。本研究的目的是观察SiO2颗粒是否对高分子复合材料的机械性能有任何影响。利用场发射扫描电镜(FE-SEM)观察复合材料的形貌。采用维氏微压痕硬度和冲击试验来测定复合材料的力学性能。压痕蠕变?研究了不同含量的纳米颗粒(SiO2)对聚甲基丙烯酸甲酯(PMMA)复合材料性能的影响。

Mechanical properties of biomass-derived silica nanoparticles reinforced PMMA composite material

Rice husk was used to produce silica particles, which were then used to reinforce the polymer matrix. The synthesized SiO2 particles were characterized using X-ray diffraction, Fourier transforms infrared spectroscopy (FTIR) and scanning electron microscopy with EDS. In a PMMA matrix, prepared SiO2 particles in amounts of 1, 3, and 5 wt.% were used as reinforcing agents. The goal of this research was to see if SiO2 particles had any effect on the mechanical properties of polymer composite materials. The morphology of the composites was examined using a field emission scanning electron microscope (FE-SEM). Vickers microindentation hardness and impact testing were used to determine the mechanical properties of the obtained composites. The indentation creep?s behavior of a polymethylmetacrylate (PMMA) composite material with varying amounts of nanoparticles (SiO2) was investigated and analyzed.
