“…Thus, the present CNT assembly may compete with CFs for high-end uses, especially in weight-sensitive applications demanding combined electrical and mechanical functionalities. A few examples to note are light-weight, high-strength and multifunctional composites for military and aerospace structure components and electrical conductors for power transmission lines 7 .…”

High-strength carbon nanotube fibre-like ribbon with high ductility and high electrical conductivity

et al. 2014

Macroscopic fibres made up of carbon nanotubes exhibit properties far below theoretical predictions and even much lower than those for conventional carbon fibres. Here we report improvements of mechanical and electrical properties by more than one order of magnitude by pressurized rolling. Our carbon nanotubes self-assemble to a hollow macroscopic cylinder in a tube reactor operated at high temperature and then condense in water or ethanol to form a fibre, which is continually spooled in an open-air environment. This initial fibre is densified by rolling under pressure, leading to a combination of high tensile strength (3.76-5.53 GPa), high tensile ductility (8-13%) and high electrical conductivity ((1.82-2.24) Â 10 4 S cm À 1 ). Our study therefore demonstrates strategies for future performance maximization and the very considerable potential of carbon nanotube assemblies for high-end uses.

“…This is due to the excellent stretchability of PEDOT/PSS fibers (16 to 21%) compared with metallic wires or carbon nanotube fibers (1 to 8%). 21,28,55 The representative thermal images that taken at 0, 0.4, 0.8 and 1.2 V cm 1 at steady state show a clear temperature increase from 28 to 52 C for the as-spun PE-DOT/PSS fiber bundle (Fig. 3c to f).…”

CitationHigh-ampacity conductive polymer microfibers as fast response wearable heaters and electromechanical actuators 2016, 4 (6) Conductive fibers with enhanced physical properties and functionalities are needed for a diversity of electronic devices. Here, we report very high performance in the thermal and mechanical response of poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT/PSS) microfibers when subjected to an electrical current. These fibers were made by combining hot-drawing assisted wetspinning process with ethylene glycol doping/de-doping can work at a high current density as high as 1.8 ⇥ 10 4 A cm 2 , which is comparable to that of carbon nanotube fibers. Their electrothermal response was investigated using optical sensors and verified to be as fast as 63 C s 1 and is comparable with that of metallic heating elements (20-50 C s 1 ). We investigated the electromechanical actuation resulted from the reversible sorption/desorption of moisture controlled by electro-induced heating.Results revealed an improvement of several orders of magnitudes compared to other linear conductive polymer-based actuators in air. Specifically, the fibers we designed here have a rapid stress generation rate (> 40 MPa s 1 ) and a wide operating frequency range (up to 40 Hz). These fibers have several characteristics including fast response, low-driven voltage, good repeatability, long cycle life and high energy efficiency, favoring their use as heating elements on wearable textiles and as artificial muscles for robotics.

Chemically converted graphene: scalable chemistries to enable processing and fabrication

et al. 2015

View full text Add to dashboard Cite

Graphene, a nanocarbon with exceptional physical and electronic properties, has the potential to be utilized in a myriad of applications and devices. However, this will only be achieved if scalable, processable forms of graphene are developed along with ways to fabricate these forms into material structures and devices. In this review, we provide a comprehensive overview of the chemistries suitable for the development of aqueous and organic solvent graphene dispersions and their use for the preparation of a variety of polymer composites, materials useful for the fabrication of graphene-containing structures and devices. Fabrication of the processable graphene dispersions or composites by printing (inkjet and extrusion) or spinning methods (wet) is reviewed. The preparation and fabrication of liquid crystalline graphene oxide dispersions whose unique rheologies allow the creation of graphene-containing structures by a wide range of industrially scalable fabrication techniques such as spinning (wet and dry), printing (ink-jet and extrusion) and coating (spray and electrospray) is also reviewed.
