Carbon Nanotube Supercapacitors | IntechOpen

2010-3-1 · 1.1. Supercapacitors and currently used supercapacitor electrode materials. The supercapacitor concept was first described in a patent filed in 1957 by Becker, who utilized a high-surface-area carbon electrode and an aqueous H 2 SO 4 electrolyte to fabricate the supercapacitors (Kötz & Carlen, 2000).In 1971, NEC (Japan) developed aqueous electrolyte-based supercapacitors …

Dispersion of Pristine CNT in UHMWPE Solution to …

2020-8-18 · CNT dispersion in polymer matrices uniformly remains a challenge. Uniform dispersion of carbon nanotube (CNT) within ultra-high molecular polyethylene (UHMWPE) solution is the first step to achieve CNT/UHMWPE fibers with excellent properties. Several approaches have been tried.

Sheath-run artificial muscles | Science

In Fig. 2B, we compare the time dependence of paddle rotation and speed for a PEO-SO 3 @CNT SRAM and HYAM and a pristine CNT muscle that are undergoing one complete reversible cycle of ethanol vapor–powered actuation. The peak stroke and peak rotation speed for the SRAM [143°/mm and 507 rotations per minute (rpm)] are about twice that for ...

Carboxylation of multiwalled carbon nanotube …

In this study, the impact of carboxylated multiwalled CNT (MWCNT-COOH) on human normal liver cell line L02 was studied and compared with pristine multiwalled CNT (p-MWCNT). The data accumulated in this study revealed that modification with carboxyl group reduced the toxicity of MWCNT on L02 cells, probably due to the decreased activation of ...

Strong, Light, Multifunctional Fibers of Carbon …

Shorter carbon nanotubes are easier to make, but, when assembled into fibers, the resulting fiber properties are much poorer than might be predicted by theory. Conversely, longer carbon nanotubes have much better properties but are harder to process. Behabtu et al. (p. [182][1]) combined the best of both worlds through scalable wet spinning method, in which they dissolved longer carbon ...
