摘要

通过形貌、光吸收和发光性能测定纳米纤维素薄膜和填充微晶纤维素或氧化石墨烯的纳米纤维素的透光率和吸光度、吸收系数、光学带隙值和厄巴赫能的光谱特性。讨论了不同添加剂对复合材料光谱特性和带隙特性的影响。结果表明，添加剂对复合材料性能影响的差异可能是由于添加剂与纳米纤维素颗粒表面相互作用的机制不同所致。

Morphology, Optical and Electronic Characteristics of Nanocellulose Filled with Microcrystalline Cellulose and Graphene Oxide

The morphology, optical absorption and luminescence properties were used to determine spectral characteristics of optical transmittance and absorbance, coefficient of absorption, the values of the optical band gap and Urbach energy of thin nanocellulose films and nanocellulose filled with microcrystalline cellulose or graphene oxide. The influence of noted additives on the spectral properties of composites and the characteristics of the optical band gap has been discussed. It was suggested that the difference in the effect of these additives on the properties of composites could be caused by different mechanisms of interaction of additives with the surface of nanocellulose particles.
