Due to difficulties in obtaining monomaterials, intensive research into the properties of ceramic compositions has been undertaken, along with developments to the properties of the compositions. These are not inferior to monomeric structures for a number of basic parameters. Among the different types of ceramics, magnesium fluoride and zinc sulfide occupy a special place due to their unique properties and specific applications. In this paper, we studied functional optoelectronics and modulating technique elements based on the advanced ceramics MgF and ZnS. The results of the transmittance spectral parameters and the contact angle estimation as well as an AFM analysis of the studied ceramics, both pure and structured with carbon nanotubes, are presented. We observed that the main characteristics of the studied materials with a surface modified by carbon nanotubes could be significantly changed when an innovative laser-oriented deposition method was applied. This method permitted the CNTs to be deposited in a vertical position on the material surface. The main features of the carbon nanotubes-such as the smaller value of the refractive index, the greater strength between the carbon atoms, and the effective surface-were taken into consideration. The analytical, quantum chemical, and experimental results of the studies of the changes in the basic physical parameters of the selected model of the inorganic matrices of the ceramics are given.
由于获取单一材料存在困难,人们对陶瓷组合物的性能进行了深入研究,并对其性能进行了改进。在一些基本参数方面,这些陶瓷组合物并不逊色于单体结构。在不同类型的陶瓷中,氟化镁和硫化锌因其独特的性能和特定的应用而占据特殊地位。在本文中,我们研究了基于先进陶瓷MgF和ZnS的功能光电子学和调制技术元件。给出了所研究陶瓷(包括纯陶瓷以及用碳纳米管结构化的陶瓷)的透过率光谱参数、接触角估计结果以及原子力显微镜分析结果。我们观察到,当应用创新的激光导向沉积方法时,表面经碳纳米管改性的所研究材料的主要特性可能会发生显著变化。这种方法使碳纳米管能够垂直沉积在材料表面。考虑了碳纳米管的主要特性,如较小的折射率值、碳原子之间较大的强度以及有效的表面。给出了对所选陶瓷无机基质模型基本物理参数变化研究的分析、量子化学和实验结果。
