“…So far, applications including sensors, catalysis, and lithography have been explored with various 3DOM structures [7][8][9][10]. Materials such as metals (Ni, Pt, Cu, Au, Ag) and compounds (SiO 2 , TiO 2 , CdS, ZnO, CeO 2 ) have been prepared in inverse opals [4,5,8,[11][12][13][14][15][16][17][18][19].…”

“…The additive could self-order at the surface of the growing nickel layer transferring its structure by inhibiting the mass transfer of nickel ions toward the surface at certain places. If micelles are formed they could attach to the surface in a closely spaced sphere packing generating a hexagonal structure comparable to nanosphere lithography as described by Lee et al 13 Attard et al were the first to report about using organic surfactants for structural templating in deposition. 37,38 In these papers non-ionic surfactants are applied in aqueous phases at typical concentrations exceeding 10 wt% to form a homogenous selfassembled liquid crystal template.…”

“…4 Of special interest in the context of our own work are processes which are able to yield porous nickel films with an ordered pore structure. To this end templating or replication processes 12 have been applied, based, for example, on colloidal monolayers 13 or anodic aluminum oxide (AAO). 14 Using a two-step replication based on AAO, 15 nickel layers with the typical honeycomb-like pore structure of this oxide material were produced.…”

A new self-organization phenomenon was observed during pulse current electrodeposition of nickel layers from an acidic sulfamate electrolyte containing a few 100 mg/l of a polymeric surfactant. Scanning electron microscopy (SEM) analysis reveals ordered arrays of nanometer sized pits. Within domain of about 1 μm size the pits arrange on a hexagonal lattice with a pore-to-pore spacing of about 120 nm. SEM inspection of cross sections show that the pits are the ends of straight nanochannels of about 40 nm diameter, extending virtually through the complete layer parallel to the growth direction. The additive is an amphiphilic polymer consisting of a backbone carrying carboxylate groups, styrene units and polyether side chains. According to current knowledge the presence of this polymer in the electrolyte and the application of special current pulse patterns are preconditions for the formation of the ordered nanopore arrays. The mechanism responsible for this kind of self-organization is still a matter of speculation but experimental results point to hydrogen nanobubbles acting as templating agents.

“…Jian‐Hong Lee et al . , followed the evolution of a metallic mask deposited on PS spheres and found the PS spheres to move as a result of metallic growth underneath, eventually resulting in a continuous metallic layer rather than a nanostructured layer. This finding offers a simple parameter that can be used to obtain a feature size smaller than the spheres used.…”

The fabrication of nanostructured materials is an area of continuous improvement and innovative techniques that fulfill the demand of many fields of research and development. The continuously decreasing size of the smallest patternable feature has expanded the catalog of methods enabling the fabrication of nanostructured materials. Several of these nanofabrication techniques have sprouted from applications requiring nanoporous membranes such as molecular separations, cell culture, and plasmonics. This review summarizes methods that successfully produce through-pores in ultrathin films exhibiting an approximate pore size to thickness ratio of one, which has been shown to be beneficial due to high permeability and improved separation potential. The material reviewed includes large-area, parallel, and affordable approaches such as self-organizing polymers, nanosphere lithography, anodization, nanoimprint lithography as well as others such as solid phase crystallization and nanosphere lens lithography. The aim of this review is to provide a set of inexpensive fabrication techniques to produce nanostructured materials exhibiting pores ranging from 10 to 350 nm and exhibiting a pore size to thickness ratio close to one. The fabrication methods described in this work have reported the successful manufacture of nanoporous membranes exhibiting the ideal characteristics to improve selectivity and permeability when applied as separation media in ultrafiltration.
