Surface Heterostructure of Aluminum with Carbon Nanotubes Obtained by Laser-Oriented Deposition

Abstract

Al is one of the most widely applicable metallic materials due to its advanced properties. However, its main drawback is its strength, which is relatively low compared to ferrous alloys. This issue may be resolved using different approaches. In the present work, a heterostructure of Al substrate with a modified surface with carbon nanotubes (CNTs) was studied. This heterostructure was obtained using the laser-oriented deposition technique. The obtained results showed a slight reduction in the reflectivity of the obtained Al substrate with embedded CNTs compared to pure Al. Additionally, the obtained surface heterostructure showed enhancement in microhardness and higher hydrophobicity. Simulation of the CNT embedding process revealed that CNT penetration strongly depends on the diameter. Hence, the penetration increases when the diameter decreases.

Nanostructuration Impact on the Basic Properties of the Materials: Novel Composite Carbon Nanotubes on a Copper Surface

“…As observed in Figure 3, the CA of the original alloy exhibits an average value o 110° and the surface with the deposited CNTs demonstrates an average value of 114 The higher hydrophobicity of the obtained thin film is addressed to the Lotus effect pro vided by the appearance of the CNTs on the surface. These results are well-correlate with the results shown before on the CNTs-deposited surface into the KBr, LiF, and A materials [23][24][25].…”

“…Van-Duong Dao et al showed the development of the new hybrid systems based on MWNT-Pt for the use of dye-sensitized solar cells [21]; moreover, this team has extended the variation of the Pt-based materials via construction of the Pt-based alloy/graphene nanohybrid for photovoltaics [22]. Kamanina et al extensively investigated laser-oriented deposition (LOD) technology for production of structural materials with the advanced surface performance [23][24][25][26][27]. KBr [23], LiF [24], Al [25] have been studied and their physical-chemical properties have been improved via application of the laser technique.…”

KBr [23], LiF [24], Al [25] have been studied and their physical-chemical properties have been improved via application of the laser technique. In each of these cases of the material processing, the ratio between the parameters of the elementary lattice of the matrix and the diameter of the nanotubes was taken into account; the expansion rate of the carbon nanotubes was also taken into account as well when an electric field was applied in the range of 100-600 V/cm.…”

Carbon Nanotubes Use for the Semiconductors ZnSe and ZnS Material Surface Modification via the Laser-Oriented Deposition Technique

“…In the current paper, the laser-oriented deposition (LOD) approach, previously shown to treat inorganic crystals and metals, such as KBr [25], BaF2 [26], and Al [27], is shown as the perspective instrument to modify the properties of the semiconductors based on ZnSe and ZnS. The possibility of the ZnS and ZnSe surfaces' modification via the vertically oriented CNTs deposition is shown.…”
