Poly(methyl methacrylate)-Fullerene (PMMA/C60) nanocomposites, with different concentrations of C60 molecules (0.025 wt.%, 0.05 wt.%, 0.075 wt.% and 0.1 wt.%), were synthesized and characterized by Magnetic Force Microscopy and UV-VIS spectroscopy. Characterization had two main objectives: to identify C60 molecules in the PMMA/C60 complex and to evaluate the order of PMMA and C60 molecules in it. Since the structural properties of PMMA/C60 complex depend on the arrangement of methyl methacrylate (MMA) and C60 molecules, it can be concluded that the structure of the complex directly correlates to the ratio of an unpaired/paired electrons within the material. To investigate the influence of different concentrations of fullerene molecules in PMMA on the attraction and the repulsion forces in material, based on paired and unpaired electrons, and ultimately on the complex structural and optical properties, Magnetic Force Microscopy was used. Investigation showed that PMMA/C60 complex with 0.025 wt.% concentration of C60 has the best structural and optical properties for applications in ophthalmology, and may be used as a new material for spectacles. UV-VIS Spectroscopic analysis in domain of 380 to780 nm showed that PMMA material with 0.025 wt.% concentration of C60 reduces UV and high blue energy light for more than 60% and in new spectral scenario ratio of blue and green spectra is changed.

具有不同浓度的C 60分子的PMMA / C 60复合材料的光学和结构性质及其可能的应用

合成了具有不同浓度的C 60分子(0.025 wt。%,0.05 wt。%,0.075 wt。%和0.1 wt。%)的聚(甲基丙烯酸甲酯)-富勒烯(PMMA / C 60)纳米复合材料,并对其进行了表征。力显微镜和紫外可见光谱。表征具有两个主要目标:鉴定PMMA / C 60配合物中的C 60分子,并评估其中的PMMA和C 60分子的顺序。由于PMMA / C 60配合物的结构性质取决于甲基丙烯酸甲酯(MMA)和C 60的排列因此,可以得出结论,复合物的结构与材料中未成对/成对电子的比例直接相关。为了研究PMMA中不同浓度的富勒烯分子对材料的吸引力和排斥力的影响,基于成对和不成对的电子,最终基于复杂的结构和光学性质,使用了磁力显微镜。研究表明,具有0.025 wt。%的C 60浓度的PMMA / C 60配合物具有最佳的结构和光学性能,可用于眼科,并可作为一种新的眼镜材料。在380至780 nm范围内的UV-VIS光谱分析表明,PMMA材料的C 60浓度为0.025 wt。% 将紫外线和高蓝色能量的光减少60%以上,并且在新的光谱方案中,蓝色和绿色光谱的比率已更改。
