“…17,18 Previously, we reported a nanoimprinting process using anodic porous alumina molds. [19][20][21] Anodic porous alumina, which is formed by the anodization of Al in an acidic electrolyte, is a typical self-ordered material. 22 The use of anodic porous alumina as a mold for nanoimprinting allows the formation of ne patterns over a large sample area owing to its naturally occurring self-ordered nanostructures.…”

“…Carbon materials with a vertical periodic structure are useful for applications as electrodes, selective absorbents and in thermal management. These materials are usually prepared by two methods, namely templating [ 26 ] and chemical vapor deposition growth. [ 27 ] In the templating method, carbon precursors (e.g., polyacrylonitrile, PDMS) are extruded into the designed template.…”

Processing 2D sheets into desired structures with high precision is of great importance for fabrication and application of their assemblies. Solution processing of 2D sheets from dilute dispersions is a commonly used method but offers limited control over feature size precision owing to the extreme volume shrinkage. Plastic processing from the solid state is therefore a preferable approach to achieve high precision. However, plastic processing is intrinsically hampered by strong interlayer interactions of the 2D sheet solids. Here, a hydroplastic molding method to shape layered solids of 2D sheets with micrometer‐scale precision under ambient conditions is reported. The dried 2D layered solids are plasticized by intercalated solvents, affording plastic near‐solid compounds that enable local plastic deformation. Such an intercalated solvent‐induced hydroplasticity is found in a broad family of 2D materials, for example graphene, MoS2, and MXene. The hydroplastic molding enables fabrication of complex spatial structures (knurling, origami) and microimprinted tubular structures down to diameters of 390 nm with good fidelity. The method enhances the structural accuracy and enriches the structural diversity of 2D macroassemblies, thus providing a feasible strategy to tune their electrical, optical, and other functional properties.

“…Similarly, as for CNTs, both catalyst-free and the deposition of catalytic NPs approaches were implemented. For the template method, different precursors were explored such as polycyclic aromatic hydrocarbons [ 221 ], polymers [ 222 , 223 ], or acetylene pyrolysis [ 224 ]. Alternatively, CNF arrays from high-aspect-ratio polymer pillars were fabricated by T. Yanagishita and H. Masuda [ 222 ].…”

The fabrication and design of carbon-based hierarchical structures with tailored nano-architectures have attracted the enormous attention of the materials science community due to their exceptional chemical and physical properties. The collective control of nano-objects, in terms of their dimensionality, orientation and size, is of paramount importance to expand the implementation of carbon nanomaterials across a large variety of applications. In this context, porous anodic alumina (PAA) has become an attractive template where the pore morphologies can be straightforwardly modulated. The synthesis of diverse carbon nanomaterials can be performed using PAA templates, such as carbon nanotubes (CNTs), carbon nanofibers (CNFs), and nanodiamonds, or can act as support for other carbon allotropes such as graphene and other carbon nanoforms. However, the successful growth of carbon nanomaterials within ordered PAA templates typically requires a series of stages involving the template fabrication, nanostructure growth and finally an etching or electrode metallization steps, which all encounter different challenges towards a nanodevice fabrication. The present review article describes the advantages and challenges associated with the fabrication of carbon materials in PAA based materials and aims to give a renewed momentum to this topic within the materials science community by providing an exhaustive overview of the current synthesis approaches and the most relevant applications based on PAA/Carbon nanostructures materials. Finally, the perspective and opportunities in the field are presented.
