Fabrication of ordered nanoporous anodic alumina prepatterned by mold-assisted chemical etching

In this article, a simple and cost-effective method to create patterned nanoindentations on Al surface via mold-assisted chemical etching process is demonstrated. This report shows the reaction-diffusion method which formed nanoscale shallow etch pits by the absorption/liberation behaviors of chemical etchant in poly(dimethylsiloxane) stamp. During subsequent anodization, it was possible to obt...

Direct fabrication of 3D graphene on nanoporous anodic alumina by plasma-enhanced chemical vapor deposition

High surface area electrode materials are of interest for a wide range of potential applications such as super-capacitors and electrochemical cells. This paper describes a fabrication method of three-dimensional (3D) graphene conformally coated on nanoporous insulating substrate with uniform nanopore size. 3D graphene films were formed by controlled graphitization of diamond-like amorphous carb...

The fabrication of ordered nanoporous metal films based on high field anodic alumina and their selected transmission enhancement.

A two-step high field anodization and a controllable barrier layer removing process have been used for the fabrication of porous anodic alumina (PAA) with different morphologies. Based on the PAAs, porous noble metal films with widely tunable pore size and inter-pore distance have been realized by a simple sputtering method. Their morphology and optical properties were studied with a field-emis...

Fabrication of a porous anodic alumina membrane

With the aim of developing a process for surface enlargement on an electrode for measuring brain activity attempts have been made to fabricate a porous anodic alumina membrane directly on the electrode. The porous membrane was intended to be used as scaffold for deposition of an electrically conducting polymer on the electrode surface. A silicon wafer with gold electrodes was the base onto whic...
