چکیده

The total electric resistance R is theoretically linearly increasing function of the conductive wire length L because the electric conductivity K or electric resistivity r is independent on L. It was found out that dependence of electric resistance R on L is highly nonlinear for yarns containing the conductive metal fibers. The main aim of this paper is creation of the simple mechanistic model describing this dependence. Characteristic parameter of this model is so called specific resistivity . This factor is used for expressing the influence of content of metal fibers on the yarns conductivity or resistivity changes.

Composite yarns of multiwalled carbon nanotubes with metallic electrical conductivity.

Unique macrostructures known as spun carbon-nanotube fibers (CNT yarns) can be manufactured from vertically aligned forests of multiwalled carbon nanotubes (MWCNTs). These yarns behave as semiconductors with room-temperature conductivities of about 5 x 10(2) S cm(-1). Their potential use as, for example, microelectrodes in medical implants, wires in microelectronics, or lightweight conductors i...

Stretchable and Highly Conductive Carbon Nanotube-Graphene Hybrid Yarns for Wearable Systems

Carbon Nanotubes (CNTs) have emerged as potential candidates for replacement of conventional metals due to their significant mechanical, electrical, thermal properties and non-oxidizing abilities [1, 2]. The density of CNT composites is about five times lower than copper and around half that of aluminium. Moreover, their thermal conductivity is about ten times that of copper. With the above men...

Fiber and fabric solar cells by directly weaving carbon nanotube yarns with CdSe nanowire-based electrodes.

Electrode materials are key components for fiber solar cells, and when combined with active layers (for light absorption and charge generation) in appropriate ways, they enable design and fabrication of efficient and innovative device structures. Here, we apply carbon nanotube yarns as counter electrodes in combination with CdSe nanowire-grafted primary electrodes (Ti wire) for making fiber and...

Enhanced mechanical strength and electrical conductivity of carbon-nanotube/TiC hybrid fibers.

We report the synthesis of carbon nanotube/TiC hybrid fibers using a polymer-assisted chemical solution approach. Ti metal ions are bound to aqueous polyethyleneimine (PEI) to form precursor solution. Amphiphilic PEI with Ti easily permeates the CNT fibers. Upon annealing in a controlled atmosphere, a homogeneous TiC network is formed in the CNT fibers. The obtained CNT/TiC hybrid fibers show p...

Hybrid nanofluid based on CuO nanoparticles and single-walled Carbon nanotubes: Optimization, thermal, and electrical properties

The purpose of this study is to use the thermal and electrical conductivities of copper oxide nanoparticles and carbon nanotubes for the preparation of high-performance nanofluids for achieving better heat transfer properties. These nanofluids consist of a water/Ethylene Glycol solution containing single-wall carbon nanotubes (SWCNTs) and copper oxide nanoparticles (CuONPs). The effects of such...
