Construction of Three-Dimensional Conductive Graphitic Architecture by Highly Efficient Electrochemical Exfoliation

Synthesis of magnetic graphene-Fe3O4 nanocomposites by electrochemical exfoliation method

Superparamagnetic few-layer graphene nanocomposites (FLG- NCs) can be used for many technological applications, such as solar cells, batteries, touch panels and supercapacitors. In this work, we applied electrochemical exfoliation method as a simple, one step and economical technique to fabricate FLG- NCs. The fabricated Superparamagnetic FLG- NCs were characterized by X-ray diffraction (XRD), ...

Graphene prepared by one-pot solvent exfoliation as a highly sensitive platform for electrochemical sensing.

Graphene was easily obtained via one-step ultrasonic exfoliation of graphite powder in N-methyl-2-pyrrolidone. Scanning electron microscopy, transmission electron microscopy, Raman and particle size measurements indicated that the exfoliation efficiency and the amount of produced graphene increased with ultrasonic time. The electrochemical properties and analytical applications of the resulting...

Construction of highly conductive nanowires on a DNA template

We present measurements of the electrical conductivity of metallic nanowires which have been fabricated by chemical deposition of a thin continuous palladium film onto single DNA molecules to install electrical functionality. The DNA molecules have been positioned between macroscopic Au electrodes and are metallized afterwards. Low-resistance electrical interfacing was obtained by pinning the n...

Covalent modification of Graphitic Carbon Substrates by Non- Electrochemical Methods

Three-dimensional highly conductive silver nanowires sponges based on cotton-templated porous structures for stretchable conductors

A stretchable cotton–Ag nanowire–poly(dimethylsiloxane) (cotton–AgNWs–PDMS) conductor was fabricated by embedding the unique binary conductive network structure of cotton–AgNWs in PDMS through a simple dip-coating method. The binary conductive network structure was constructed based on cotton which had an interconnected and junction-free macroporous structure as the skeleton to support the two ...
