This study addresses a combination of a well-developed and mild dispersion method and high-quality arc discharge single-walled carbon nanotubes (SWCNTs) as starting materials. Thus, we advance in fabrication of transparent, conducting films with extraordinary low material loss during SWCNT processing. The starting material was characterized by means of thermogravimetric analysis, high-resolutio...

Mechanical abrasion is an extremely simple, rapid, and low-cost method for deposition of carbon-based materials onto a substrate. However, the method is limited in throughput, precision, and surface compatibility for drawing conductive pathways. Selective patterning of surfaces using laser-etching can facilitate substantial improvements to address these current limitations for the abrasive depo...

BACKGROUND Nowadays significant attention is to nanocomposite compounds in water cleaning. In this article the synthesis and characterization of conductive polyaniline/clay (PANI/clay) as a hybrid nanocomposite with extended chain conformation and its application for water purification are presented. METHODS Clay samples were obtained from the central plain of Abhar region, Abhar, Zanjan Prov...

Single wall carbon nanotubes (SWCNTs) are coated with polyvinylpyrrolidone-iodine (povidone-iodine or PVPI) in water. This solution of SWCNTand PVPI is deposited as a composite film, composed of individual and bundled SWCNTs with a PVPI coating. This material acts as a conductive nanotextured bandage with high flexibility and self contained slow-release antiseptic iodine. Antibacterial properti...

Graphene and single-walled carbon nanotube (SWCNT) have been widely studied because of their extraordinary electrical, thermal, mechanical, and optical properties. This paper describes a novel and flexible method to fabricate all-carbon field-effect transistors (FETs). The fabrication process begins with assembling graphene grown by chemical vapor deposition (CVD) on a silicon chip with SiO2 as...

Single-walled carbon nanotubes (SWCNTs) were patterned using inkjet printing. To make the uniform networks of dropped SWCNTs, the effects of substrate heating, surface hydrophilicity of the substrate and the jetting process were investigated. Circuit diagrams including holes, lines and curves were printed on glass and polymer substrates, and the conductive lines were printed on a glass substrat...

An efficient photocatalytic material TiO2/Pt was prepared via the sonochemical synthesis followed by the thermal treatment. The TiO2/Pt nanocomposite was able to photocatalytically degrade the azo dye methylene blue (MB) under UV (ultraviolet) and Vis (visible) irradiation. The enhanced photocatalytic activity of Pt/TiO2 for methylene blue degradation is attributed to the following factors; to ...

A new shape memory nanocomposite that exhibits rapid electrical actuation capabilities is fabricated by incorporating continuous, non-woven carbon nanofibers (CNFs) into an epoxy based SMP matrix. The fiber morphology and nanometre size provide a percolating conductive network with a large interfacial area. This not only gives high electrical conductivity but also simultaneously enhances heat t...

A 3D mechanically stable scaffold is shown to accommodate the volume change of a high-specific-capacity nickel-tin nanocomposite during operation as a Li-ion battery anode. The nickel-tin anode is supported by an electrochemically inactive conductive scaffold with an engineered free volume and controlled characteristic dimensions, which engender the electrode with significantly improved cyclabi...

In this paper we demonstrate that layer-by-layer (LbL) films of polyamidoamine (PAMAM) dendrimers and single-walled carbon nanotubes (SWCNTs) are efficient for controlling the morphology of electrogenerated cobalt (Co) and the platinum-cobalt (PtCo) alloy. While Co grew to the micrometer scale and poorly covered the ITO substrate, with the LbL matrix it was kept in the nanoscale regime and prov...
