Electromagnetic interference (EMI) shielding of single-walled carbon nanotube epoxy composites.
Single-walled carbon nanotube (SWNT)-polymer composites have been fabricated to evaluate the electromagnetic interference (EMI) shielding effectiveness (SE) of SWNTs. Our results indicate that SWNTs can be used as effective lightweight EMI shielding materials. Composites with greater than 20 dB shielding efficiency were obtained easily. EMI SE was tested in the frequency range of 10 MHz to 1.5 ...
متن کاملTitle : PMMA / carbon nanotube nanocomposites foams for EMI shielding application
With the rapid development of gigahertz electronic systems, electromagnetic pollution has become a serious problem, which justifies a very active quest for effective electromagnetic interferences (EMI) shielding materials. Polymers filled with carbon fillers have been widely investigated for EMI shielding purposes because of unique combination of electrical conductivity and polymer flexibility....
متن کاملEffect of Carbon Nanotube and Surfactant on Processing, Mechanical, Electrical and EMI-Shielding of Epoxy Composites
Dispersing nanoparticles in a polymer matrix is intrinsically challenging due to unfavorable entropic interactions between the matrix and the nanoparticle. In this research dispersion of nanoparticles in polymer matrix was studied and the effect of dispersion on properties was investigated. The properties of polymer composite depend on the type, size, shape, concentration of nanoparticles, and ...
متن کاملPalladium Nanoparticles Decorated Single-Walled Carbon Nanotube Hydrogen Sensor
We developed a simple and cost-effective fabrication technique to construct a hydrogen nanosensor by decorating single-walled carbon nanotubes with Pd nanoparticles. By varying the sensor’s synthesis conditions (e.g., Pd electrodeposition charge, deposition potential, and initial baseline resistance of the SWNT network), the sensing performance was optimized. The optimized sensor showed excelle...
متن کاملPreparation and Characterization of Cobalt Nanoparticle-Decorated Multi-Walled Carbon Nanotubes
In order to increase gas storage capacity such as hydrogen and methane, various wt% of cobalt were decorated on the surface of MWCNTs which was already treated nitric and sulfuric acids to provide functional groups on the surface of MWCNTs. The characteristic peak of SO4 in FT-IR spectrum was at 1220 cm, which was resulting from sulfuric acid treatment. This peak implies that acid treatment con...
