The abundance and the versatility of the cellulose structure based on the route of modification have attracted many researchers in the scientific community. Cellulose can be taken from many natural sources, but the largest source of natural cellulose is plant parts. Chemically treated cellulose can show properties that are not displayed by untreated natural cellulose. In this study, cellulose was treated and was characterized using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy, fluorescence spectroscopy and ultraviolet–visible (UV–Vis) spectroscopy, and its optical and dielectric properties were studied. The characterization showed rice-grain-like structures in the SEM image; the particle size analysis data revealed that the particle size ranged from 0.474 to 8.198 μm; the absorbance was at 218.0 and 218.5 nm under UV–Vis spectroscopy; and sharp peaks at 445.19 nm and excitation at 666.47 nm were observed under fluorescence spectroscopy. The study indicated that treated cellulose showed change in color on exposure to UV radiation, and the dielectric study indicated the possibility of the use of treated cellulose in charge-storage devices.

化学处理纤维素的介电和光学性质

基于修饰途径的纤维素结构的丰富性和多功能性吸引了科学界的许多研究人员。纤维素可以从许多天然来源中获取，但是天然纤维素的最大来源是植物部分。化学处理的纤维素可以显示未经处理的天然纤维素无法显示的特性。在这项研究中，使用扫描电子显微镜（SEM），傅立叶变换红外光谱，荧光光谱和紫外可见（UV-Vis）光谱对纤维素进行了处理和表征，并对其光学和介电性能进行了研究。表征在SEM图像中显示出米粒状结构。粒度分析数据表明，粒度为0.474至8.198μm。吸光度分别为218.0和218。在紫外-可见光谱下为5 nm；在荧光光谱下观察到了在445.19nm处的尖峰和在666.47nm处的激发。研究表明，处理过的纤维素在暴露于紫外线辐射后会发生颜色变化，而电介质研究表明，在电荷存储设备中使用处理过的纤维素的可能性。
