Anodic Oxide Films and Nanoporous Templates for Electronics and Corrosion Protection
This research community focuses on the electrochemical formation of protective oxide layers on metals, specifically aluminum and titanium, and the engineering of these layers into precise nanoporous structures. These films serve as durable barriers against corrosion in industrial applications and as nanoscale templates for manufacturing sensors, capacitors, and other electronic components.
The work centers on controlling the anodization process to create uniform, ordered pore arrays in aluminum oxide and titanium dioxide. Key methodologies include varying electrolyte compositions, such as sulfuric and oxalic acids, and adjusting voltage parameters to tune pore size and depth. The resulting materials are characterized for their corrosion resistance, dielectric properties, and structural integrity. Applications range from aerospace alloy protection and electrolytic capacitor dielectrics to the fabrication of nanowire arrays and optical filters. The community also investigates the fundamental mechanisms of oxide growth, including the role of fluoride ions and the influence of substrate crystallography on film morphology.
The largest share of this community's output is found in aluminium research, accounting for 1.6% of all aluminium research, with 2,446 papers in this group. Tantalum research also features prominently, representing 1.7% of that element's total research output with 645 papers.
The community comprises 8,599 papers, published primarily in the Journal of The Electrochemical Society, Electrochimica Acta, and Thin Solid Films. Recent work continues to refine the fabrication of through-hole anodic aluminum oxide membranes and investigates the long-term degradation of aluminum electrolytic capacitors using physics-informed neural networks.
