Carbon nanotube (CNT)-based electrodes in flexible supercapacitors have received significant attention recent years. fiber fabrics (CNT-FF) emerged as promising materials due to their high surface area, excellent conductivity, and mechanical strength. Researchers attempted improve the energy density rate performance of CNT-FF supercapacitor through various strategies, such functionalization wit...

The development of chemical doping methods for carbon nanotubes (CNTs) is essential various electronic applications. However, typical p-doping CNT thin-film transistors (TFTs), using oxygen and water from the atmosphere, are quite sensitive to changes in surrounding environment, thus, their poor temperature tolerance a critical problem during device fabrication. As p-dopant CNT–TFTs, we used 1,...

This paper describes the application of electrical impedance tomography (EIT) to demonstrate the multifunctionality of carbon nanocomposite thin films under various types of environmental stimuli. Carbon nanotube (CNT) thin films are fabricated by a layer-by-layer (LbL) technique and mounted with electrodes along their boundaries. The response of the thin films to various stimuli is investigate...

The fabrication of iron and carbide nanoparticles (NPs) for catalytic reactions such as the growth carbon nanotubes (CNTs) compete with challenge covering a wide range substrates perfect control NP reactivity. We present in this work novel atomic layer deposition (ALD) process to grow Fe/Fe 3 C thin films over silica flat substrates. depositions were carried out exposing surface through various...

There is a strong interest in thin, flexible energy storage devices to meet modern society needs for applications such as interactive packaging, radio frequency sensing, and consumer products. In this article, we report a new structure of thin, flexible Li-ion batteries using paper as separators and free-standing carbon nanotube thin films as both current collectors. The current collectors and ...

A submicroscale flow sensor has been developed that consists of a suspended hot film and carbon nanotube (CNT) fins. Flow measurement experiments, together with a theoretical model, revealed the advantages of the use of CNT fins. The suspended metal film reduces heat loss and the CNT fins enhance the heat transfer to the fluid flow. Herein, the working principle of the CNT fins is presented in ...

Three-component organic/inorganic hybrid films were fabricated by drop-casting the mixed dispersion of nanodispersed-poly(nickel 1,1,2,2-ethenetetrathiolate) (nano-PETT), polyimide (PI) and super growth carbon nanotubes (SG-CNTs) in N-methylpyrrolidone (NMP) at the designed ratio on a substrate. The dried nano-PETT/PI/SG-CNT hybrid films were prepared by the stepwise cleaning of NMP and methano...

We report a novel self-rolling, conductive, and biocompatible multiwall carbon nanotube (MWCNT)-dopamine-polyethylene glycol (PEG) hydrogel film. The gel can self-fold into a thin tube when it is transferred from a glass slide to an aqueous environment, regardless of the concentrations of the MWCNT. The film presents a highly organized pattern, which results from the self-assembly of hydrophili...
