“…In particular, a “top-down” approach relies on the exploitation of externally controlled parameters to build up a nanostructured architecture starting from larger dimensions [ 11 ]. Conversely, a “bottom-up” approach involves the growth of (sub)nanometer components (i.e., colloids, (macro)molecules, or even atoms) to produce complex nanoarchitectures [ 12 ].…”

Highly ordered porous coatings find applications in many fields, such as nanotechnology, microfluidics and nanofluidics, membrane separation, and sensing. In recent years, there has been great interest regarding the synthesis of isoporous and well-ordered (in)organic coatings for the production of highly selective functional membranes. Among the different strategies that have been proposed to date for preparing these porous thin coatings, one simple route involves the use of self-assembled amphiphilic block copolymers either as the porogen (acting as sacrificial templating agents for the production of inorganic architectures) or as a source of the porogen (by self-assembly for the production of polymeric substrates). Therefore, an extended discussion around the exploitation of block copolymers is proposed here in this review, using polystyrene-block-polyethylene oxide (PS-b-PEO) as the model substrate, and critical points are highlighted.

“…In addition, advanced anodization protocols, including hard anodization [12,13], pulsed or sequential anodization [14], or lithography-guided anodization [15] allowed recently to obtain ideally ordered nanoporous templates, exhibiting also pore diameter * corresponding author; e-mail: vmpp@uniovi.es modulations [16,17]. The spatial and periodic pores arrangement of the AAO templates, together with the confined growth of the magnetic material at the nanoscale deposited in the nanoporous alumina template, translate into the appearing of cooperative phenomena in the nanostructured materials, which in turn lead to tailor novel functional properties that differ from that of 3D bulk and 2D thin film systems [18,19].…”

Template Assisted Deposition of Ferromagnetic Nanostructures: from Antidot Thin Films to Multisegmented Nanowires

et al. 2017

The growth of nanostructured materials by means of different deposition methods employing nanoporous anodic aluminum oxide membranes as patterned templates has been widely used during last years due to the outstanding features displayed by these nanoporous templates. Here we report on the synthesis, morphology and magnetic properties exhibited by novel magnetic 1D and 2D nanostructured materials having nanowire or antidot thin films geometry, respectively, together to that of geometrically diameter modulated ferromagnetic nanowires. Their magnetic properties will be analyzed and discussed based on the different anisotropic behavior derived from their morphological and microstructural features.
