Electrochemical Characterization of Single-Walled Carbon Nanotube Electrodes

Electrochemical determination of cadmium and lead on pristine single-walled carbon nanotube electrodes.

A flexible, transparent, single-walled carbon nanotube (SWCNT) film electrode was prepared by vacuum filtering methods, followed by photolithographic patterning of a photoresist polymer on the SWCNT surface. The morphology of the SWCNT film electrode surface was characterized using a field-emission scanning electron microscope coupled to an energy-dispersive X-ray spectrophotometer. The electro...

Capacitor Properties of Pure Single-walled Carbon Nanotube Electrodes

Introduction Electric double layer capacitors (EDLCs) have excellent properties in power density and durability compared with secondary batteries. Recently, development of advanced capacitors with high energy density is active because the storage devices with high power density have huge market in the fields of hybrid vehicles, mobile instruments and so on. The singlewalled carbon nanotubes (SW...

Molecular electronic devices based on single-walled carbon nanotube electrodes.

As the top-down fabrication techniques for silicon-based electronic materials have reached the scale of molecular lengths, researchers have been investigating nanostructured materials to build electronics from individual molecules. Researchers have directed extensive experimental and theoretical efforts toward building functional optoelectronic devices using individual organic molecules and fab...

Flexible, transparent single-walled carbon nanotube transistors with graphene electrodes.

This paper reports a mechanically flexible, transparent thin film transistor that uses graphene as a conducting electrode and single-walled carbon nanotubes (SWNTs) as a semiconducting channel. These SWNTs and graphene films were printed on flexible plastic substrates using a printing method. The resulting devices exhibited a mobility of ∼ 2 cm(2) V(-1) s -1), On/Off ratio of ∼ 10(2), transmitt...
