Zirconia nanotube coatings - UV-resistant superhydrophobic surfaces

Strategy facilitating the transfer of zirconium-oxide nanotubes onto zirconia-based ceramic implants

“…[21] Herein, we fabricate ZrNT films via a one-pot synthesis in the presence of a fluoride-based organic electrolyte as demonstrated in our previous works. [5][7] [5][5]The geometry and crystal structure are shown in Figure 1.The as-anodized ZrNT film shows an average film thickness of ≤ 5μm and tube diameter in the range of (50-70 nm). The films are amorphous ZrO2 in the as-anodized state and in accordance with previously reported research.…”

“…[1][2][3] Nanostructured architectures offer the possibility of creating storage units whilst improving bio-integration and functionality as a result of superior adhesion and robust reactivity. [4][5][6] Recent reports on triggered release from nanotubes is indicative of such surfaces being capable of enhanced control and response to stimuli, thereby offering the possibility of developing 'smart' multi-functional surfaces. [7] [8] Electrochemical anodization is an efficient way to develop nanostructures on a material's surface, unfortunately fabrication by anodization is restricted to valve metals.…”

“…[20] Herein, we fabricate ZrNT films via a one-pot synthesis in the presence of a fluoride-based organic electrolyte as demonstrated in our previous works. [5] [15] As shown in Figure 1 (Anodization of Zirconium: SEM micrographs -(a) nanotubes with circular morphology, (b) film thickness (cross-sectional area < 5 microns) and (c) ZrO 2 -XRD). The asanodized ZrNT film is made of amorphous ZrO 2 as reported elsewhere.…”

[4][5][6] Electrochemical anodization is an efficient way to develop nanostructures, unfortunately limiting fabrication extent to valve-metals. Non-metals, especially biomaterials are often metal-oxides and ceramics such as in the field of dental and orthopedic applications.…”

Wetting Behavior of Zirconia Nanotubes

“…catalysis, filtration or coatings. [5], [6], [7] [22] Zirconia is a biocompatible, high bandgap material that has reportedly demonstrated superior surface properties for the enhanced attachment of molecules. [8], [9], [10] It is used in biomedical devices, sensors and more recently for photocatalytic applications.…”
