Designing of epoxy composites reinforced with carbon nanotubes grown carbon fiber fabric for improved electromagnetic interference shielding

“…high magnetization) and electrical properties (enhanced conductivity) expected to improve the EM energy absorption and dissipation capability resulting in enhancement of microwave shielding effectiveness. 11 EMI shielding measurements were taken on rectangular strips of composites inside the home made sample holder. The holder matches the internal dimensions of X-band (8.2-12.4 GHz) waveguide placed between the two ports of vector network analyzer.…”

Carbon Nanotubes Functionalized in Oxygen and Water Low Pressure Discharges used as Reinforcement of Polyurethane Composites

“…Addition of CNTs can not only improve its mechanical properties but also modify its electrical properties and help with a problem of electromagnetic interference shielding. [15][16][17] …”

Electrical conductivity of carbon-nanotube/cellulose composite paper

“…Our T 0 and T 1 were close to those for SWCNT composites 8 and MWCNT composites. 14,16,20 As mentioned before, the tunnel width w and barrier height V 0 can be estimated from T 0 and T 1 . Kim et al 11 and Mdarhri et al 19 used approximate expressions for T 0 and T 1 .…”

“…8 On the other hand, the FIT model matches the electrical conductivities of multiwalled ͑MW͒ CNT composites. [14][15][16][17][18][19][20] The electrical conduction through the CNT-CNT junctions dominates the conductivity of CNT network in the FIT model. The tunnel width w and barrier height V 0 can be estimated from two specific temperatures T 0 and T 1 obtained by fitting the FIT law to the measured temperature dependence of the conductivity.…”
