Optimization of Magnetic Field-Assisted Synthesis of Carbon Nanotubes for Sensing Applications

Abstract

One of the most effective ways of synthesizing carbon nanotubes is the arc discharge method. This paper describes a system supported by a magnetic field which can be generated by an external coil. An electric arc between two electrodes is stabilized by the magnetic field following mass flux stabilization from the anode to the cathode. In this work four constructions are compared. Different configurations of cathode and coils are calculated and presented. Exemplary results are discussed. The paper describes attempts of magnetic field optimization for different configurations of electrodes.

Analysis of resistance to bending of metal electroconductive layers deposited on textile composite substrates in PVD process

“…The production of elastic electronics is possible in spray coating processes using carbon nanotubes, graphene flakes or nanofibers, electroless plating, sputtering, physical vacuum deposition, plasma coating or digital printing 4,[8][9][10][11][12][13] . To fabricate the electroconducting elements on or in textile substrates the varied methods are usually used: the embroidery 14 , dip coating 15 , electrospinning 16 , electroless plating 17,18 , ink-jet or screen printing method 19,20 , thin metallic wires or yarns 3 , metal-coated fibres 21,22 , conductive fibers produced by doping intrinsically conductive polymers 23 , the fibers with metallic core and the outer polymer coating, and even with the liquid metal core 24 , sputtering [25][26][27] or chemical and physical vacuum deposition 2,7 .…”

Laser-Textured Rubbers with Carbon Nanotube Fillers

“…New polymeric materials containing carbon nanotubes as fillers [11,12], such as acrylonitrile rubber (NBR), styrene butadiene rubber (SBR), and elastomers, require surface treatment to functionalize their properties for a wider range of engineering applications (including hydraulics, pneumatics, machine components, and in the automotive industry). Various surface treatment technologies can be used to obtain specific surface morphologies.…”
