Abstract: Different, electromagnetic, interference, (EMI), shielding, materials, have been, developed, over, time., In, the, past, electromagnetic, (EM), shielding, technology, made, use, of, metals, and, their, composites, because, of, good, shielding, effectiveness, but, their, low, elasticity high, density and, corrosion, tendency, render, them, obsolete., Ceramic-based, composites, have, also, gained, popularity, for, EMI, shielding, applications, because, of, their, low, density, and, excellent, corrosion, resistance, but, high, absorption, loss, is, a, major, drawback., Recently,, polymer-based, composites, have attracted, attention, because, they make for superb EMI shielding with the advantages of electromagnetic wave absorption over reflection, and have been widely used with fast growth in application after their emergence. This, paper, reviews, the progress, of, polymer-based, composites, as, efficient, materials, for, electromagnetic, interference, shielding and applications. Electromagnetic, (EM), waves, are, formed, by, the, interaction, of, an, electric, field, and, a, magnetic, field., EM, waves, require, no, specific, medium, through, which, they, can, move., Their, movement, can, be, though, air,, solid, materials,, liquid,, or, even, vacuum., The, EM, spectrum, ranges, from, lower, energy, waves, (longer, wavelengths),, such, as, radio, waves, and, microwaves,, to, higher, energy, waves, (shorter, wavelengths),, such, as, gamma, rays, and, X-rays., Traditional, materials, such, as, metals, and, ceramics, were, found, to, be, useful, as, EMI, shielding, materials., However,, low, elasticity,, high, density, and, high, absorption, loss, tend, to, limit, their, EMI, effectiveness., Recently,, polymer-based, electromagnetic, shielding, materials, have, been, widely, employed, as, EMI, shielding, materials., Given, the, above,, different, EMI, shielding, materials, based, on, diverse, matrix, materials, are, discussed, with, emphasis, on, polymer-based, composites, as, emerging, and, alternative, EMI, shielding, materials. The, development, of, the, electronic, industry, offers, weight, reduction, as, an, additional, technical, requirement, besides, good, EMI, shielding, performance., EMI, shielding, ensures, the inhibition, of, the, transmission, of, EM, waves, from, one, point, to, another, using, shield, materials., Metals, as, conventional, EMI, shielding, materials, have been, substituted, with, alternative, materials, which, are, lighter, such, as, polymer-based, materials, and, ceramic-based, materials. |
