Advanced Nanostructured Materials in Electromagnetic Interference Shielding

Fabrication of N-Doped Reduced Graphite Oxide/MnCo2O4 Nanocomposites for Enhanced Microwave Absorption Performance

“…EMI SE of a material represents its ability to attenuate electromagnetic radiation through absorption, reflection, and multiple internal reflections. 1,71 As a result, total shielding efficiency (SE T ) is a sum of absorption shielding efficiency (SE A ), reflection shielding efficiency (SE R ), and multiple internal reflection shielding efficiency (SE M ), that is,…”

“…The electromagnetic waves (EM) of different frequencies originating from electronic devices such as smartphone, television, radio, gamin consoles, computer, etc., interfere with one another and decline their efficiency in terms of speed, loss of data storage, as well as time. 1 In addition, exposure of EM waves to human beings adversely affects health and leads to many diseases like brain cancer, miscarriage, and leukemia. 2 Therefore, numerous efforts have been made to develop highperformance EM wave shielding materials.…”

Reduced Graphene Oxide/Fe3O4/Polyaniline Ternary Composites as a Superior Microwave Absorber in the Shielding of Electromagnetic Pollution

“…Several carbonaceous materials, such as carbon black, graphite, reduced graphene oxide, carbon nanotube (CNT), and carbon nanofiber (CNF), have also been investigated in EMI shielding applications. 3 , 13 , 14 Among them, carbon black/graphite exhibit poor dispersability and high percolation threshold leading to their poor EMI shielding performance. 15 , 16 In contrast, other carbonaceous materials explicitly are not preferred in EMI shielding due to their cost, purification, and prolonged functionalization steps.…”

“…The interference of electromagnetic wave (EM) is an undesirable manifestation of radiation originating from different electronic instruments/appliances at different frequencies. − As a result, their performance is effected in terms of speed and secrecy resulting in the loss of data storage, revenue, efforts, and time. , In addition, it also effects human health leading to leukemia, miscarriages, brain cancer, and, in some cases, even death. , Therefore, a considerable amount of research has been focused on developing suitable electromagnetic interference (EMI) shielding materials for suppression of such electromagnetic pollution either by reflection, absorption, or multiple reflections.…”

Functionalized Graphene/Nickel/Polyaniline Ternary Nanocomposites: Fabrication and Application as Electromagnetic Wave Absorbers

“…The interference of electromagnetic (EM) waves of different frequencies originating from electronic devices deteriorates their performance. − Further, these emitted EM waves have an adverse effect on human health. In view of this, several materials have been developed to block environmental pollution due to EM wave interference through reflection, absorption, and multiple internal reflection mechanisms.…”
