Obtaining of carbon nanowalls in the plasma of radio-frequency discharge

Direct fabrication of high-quality vertical graphene nanowalls on arbitrary substrates without catalysts for tidal power generation

“…It is the most commonly used method for preparing VGN, which can prepare VGN with large areas and controllable thickness. [16][17][18][19] For example, Zhou et al recently realized controllable growth of VGN through which the thickness and roughness of VGN can be precisely controlled by controlling the growth time, on Ti/quartz glass surfaces with a maximum size of 30 mm × 30 mm through the PECVD method. 20 However, due to plasma bombardment, the use of traditional PECVD deposition systems may lead to more defects in VGN, as well as a larger number of internal amorphous structures and sp 3 bonds, which makes it difficult to prepare high-quality VGN structures and limits the application of VGN.…”

Morphological characterization of carbon nanowalls networks using Minkowski functionals

“…Among nanomaterials, carbon nanowalls (CNWs) are of particular interest for research due to the large specific surface area, mechanical strength, attractive electrical, optical and other properties. [19][20][21][22][23] Most scientists suggest using CNWs for practical applications, in particular for the creation of solar cells, [24][25][26][27] light-emitting diodes, 28,29) sensors, 30,31) superhydrophobic coatings, 32,33) supercapacitors, [34][35][36] storage devices, [37][38][39] black body coating, 40) photo-electrochemical water splitting 41) and etc.…”

“…[19][20][21] The morphology of such nanostructure as CNWs is unique and the study of its properties for further practical applications is a very urgent task. The morphology is assessed using various analytical devices, in particular, scanning electron microscopy and scanning probe microscopy, 23,42) however the analysis of the obtained results requires additional tools, in particular special software and methods. Today, the above tasks are solved using the Minkowski functionals and fractal analysis, which provide information about the geometry of the structure and morphology of the nanomaterial.…”
