This communication reviews current developments in carbon nanostructure-based composite materials for electromagnetic interference (EMI) shielding. With more and more electronic gadgets being used at different frequencies, there is a need for shielding them from one another to avoid interference. Conventionally, metal-based shielding materials have been used. But due to the requirement of light weight, corrosion resistive materials, lot of work is being done on composite materials. In this research the forerunner is the nanocarbon-based composite material whose different forms add different characteristics to the composite. The article focusses on composites based on graphene, graphene oxide, carbon nanotubes, and several other novel forms of carbon.

“…The mixture was kept in a 60 • C water bath for 3 h. After cooling, it was sonicated for 30 min and filtered through a filter paper. The extract was diluted using 50 mM borate buffer (pH 9.2) at a ratio of 20 (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) prior to CE analysis.…”

“…As a rigid and water-insoluble polymer, epoxy is a promising material in the fabrication of CNT-based composite electrodes because it can be facilely produced by in situ polycondensation [19]. Various CNT-epoxy composites have been prepared by polycondensation [20][21][22]. Because the content of CNTs in these composites was less than 10% w/w, it was not suitable for the fabrication of detection electrode owing to its low electric conductivity.…”

“…Carbon materials can be heated by microwaves because of delocalized π electrons, which are free to move within the orbital structure of carbon. As the carbon continue to absorb the microwave energy, the kinetic energy of delocalized π electron increased and thus each carbon atom started to vibrate and move 47 . These actions caused the heat to generate volumetrically after absorbing the microwave energy and thus temperature of carbon materials increased.…”

Silicon carbide nanotube (SiCNTs) has been proven as a suitable material for wide applications in high power, elevated temperature and harsh environment. For the first time, we reported in this article an effective synthesis of SiCNTs by microwave heating of SiO 2 and MWCNTs in molar ratio of 1:1, 1:3, 1:5 and 1:7. Blend of SiO 2 and MWCNTs in the molar ratio of 1:3 was proven to be the most suitable for the high yield synthesis of β-SiCNTs as confirmed by X-ray diffraction pattern. Only SiCNTs were observed from the blend of MWCNTs and SiO 2 in the molar ratio of 1:3 from field emission scanning electron microscopy imaging. High magnification transmission electron microscopy showed that tubular structure of MWCNT was preserved with the inter-planar spacing of 0.25 nm. Absorption bands of Si-C bond were detected at 803 cm -1 in Fourier transform infrared spectrum. Thermal gravimetric analysis revealed that SiCNTs from ratio of 1:3 showed the lowest weight loss. Thus, our synthetic process indicates high yield conversion of SiO 2 and MWCNTs to SiCNTs was achieved for blend of SiO 2 and MWCNTs in molar ratio of 1:3.
