Electro-mechanical properties of polyurethane composite with carbon nanotubes network oxidized by KMnO4 and O2 RF plasma
Original language description
The effect of functionalization of multi-walled carbon nanotubes using KMnO4 oxidation and oxygen plasma treatment on the electrical resistance of nanotube network/polyurethane composite subjected to elongation has been studied. The layered composite isprepared by taking a non-woven polyurethane filtering membrane which is made by electrospinning, enmeshing it with carbon nanotubes and melding them into one. The testing has shown tenfold composite resistance increase for the composite prepared from KMnO4 oxidized nanotubes in comparison to the network prepared from pristine nanotubes. The evaluated sensitivity of the treated composite in terms of the gauge factor increases linearly with strain from values around 5 at the start of deformation to nearly45 at the strain 12 %. This is a substantial increase, which put the composite prepared from KMnO4 oxidized nanotubes among ranges the materials and strain gauges with the highest sensitivity of electrical resistance measurement.
