Fabrication of a metal oxide layer on a multi-walled carbon nanotube surface by in-flight coating using gas-phase deposition

Photocatalytic Anatase TiO2 Thin Films on Polymer Optical Fiber Using Atmospheric-Pressure Plasma

“…Indeed, when employing TTIP with the setup described in the present work, powdery and poorly crystalline coatings with low adherence and low photocatalytic degradation rates were obtained (Figure S8). Such observation is consistent with previous PECVD results, which reported the formation of dense and smooth coatings when using TEOT and rough coatings composed of nanoparticles when using TTIP . Previous works also reported that TiO 2 thin film growth mechanisms, responsible for the resulting chemistry, crystallinity, and morphology of the films, are influenced by the length of the precursor’s alkoxy groups.…”

UV-Protective TiO2 Thin Films with High Transparency in Visible Light Region Fabricated via Atmospheric-Pressure Plasma-Enhanced Chemical Vapor Deposition

“…In these three processes, diffusion is closely related to the film roughness because this step determines the size of aggregations. In general, the substrate temperature and precursor concentration have dramatic effects on the diffusion process, and a high substrate temperature and precursor concentration can reduce roughness. , Therefore, in this section, we will discuss the effect of these two factors on film roughness and UV-protective performance.…”

“…As a result, as shown in Table , the TiO 2 film roughness decreased when the feed TTIP concentration increased from 2.3 to 5.2 ppm. When the films were prepared with a lower feed precursor concentration, incoming clusters could easily migrate to form large aggregates, leading to the formation of a rough film . On the other hand, when the feed precursor concentration increased, more clusters were deposited on the substrate.…”

“…When the films were prepared with a lower feed precursor concentration, incoming clusters could easily migrate to form large aggregates, leading to the formation of a rough film. 56 On the other hand, when the feed precursor concentration increased, more clusters were deposited on the substrate. They bonded to each other immediately and formed larger clusters, which experience more difficulty migrating across the substrate surface, 54 thus avoiding the generation of large aggregations and resulting in a relatively smooth film (Figure S8 in the Supporting Information).…”

Engineering of the structural and morphological characteristics of MWCNTs employing a nano-dimensional binary oxide coating with enhanced thermal oxidation resistance properties for the tailoring of their reinforcement potential

“…4,29 Moreover, since the achievement of scalable design plays a key role in harnessing the true technological potential of integrated CNT-inorganic oxide nanostructures, it is of prime significance to initially search for targeted and convenient synthesis strategies supporting the rational, delicate, and tunable assembly of nano-hybrid architectures. 30,31 In the above context, it is convenient to note that several ''coating technologies'' have recently arisen as useful tactics to make a straightforward and direct attempt at the selective co-axial deposition of a thin inorganic oxide passivation layer on CNT networks, thereby supporting the evolution of high-performance nanohybrid architecture with optimized synergistic properties. 28,32,33 In particular, in the specialized case of wet chemical approaches, researchers mostly rely on hydrothermal treatment, sol-gel processing, electrodeposition techniques, etc.…”
