Background: X-band microwaves, which are part of electromagnetic waves, have various applications, such as satellite communications, radar, navigation, air traffic control, marine functions, and weather stations. Therefore, many workers are exposed to these waves in the workplace. Previous studies showed that these frequencies have adverse health effects. In occupational health, the use of shielding as an engineering measure is a priority in controlling radiation in the workplace.

“…In our study, the epoxy thick plates showed a good dielectric constant because tan θ was very small or σ ωε (30). Based on these findings, the dielectric loss of the epoxy plates and frequency were the main factors in the increased reflection loss in this study (28,29).…”

“…This allows obtaining a conductive material with a strength enough for constructional applications for aircraft industry. Although one can find similar solutions of conducting/dielectric polymeric mixtures [35][36][37][38], none of them were dedicated for effective LSP solutions in aircraft. Moreover, multidisciplinary structured approach to the problem which includes advanced modelling of appropriate percolation systems with use of experimentally determined material properties, analytical and numerical thermo-electro-mechanical simulations of material behavior in various in-service conditions and during the lightning strike and further models updating will allow achieving and manufacturing of optimized material for LSP applications.…”

The paper focuses on development of a multifunctional material which allows conducting of electrical current and simultaneously holds mechanical properties of a polymeric composite. Such material could be applied for exterior fuselage elements of an aircraft in order to minimize damage occurring during lightning strikes. The concept introduced in this paper is presented from the points of view of various scientific disciplines including materials science, chemistry, structural physics and mechanical engineering with a discussion on results achieved to-date and further plans of research.

“…As a conducting polymer, Polyaniline (PAni) has showed broad prospect of applications in various fields such as diode, electrochromism, sensor, secondary battery and electromagnetic shielding [1][2][3][4][5][6]. In spite of various advantages, PAni has received limited applications because it is neither completely soluble nor fusible in organic solvents as well as water.…”

Present paper reports novel synthesis of MgB2 doped Polyaniline (PAni). PAni is synthesized through oxidative polymerization method using Ammonium Peroxodisulphate and doped by different compositions of MgB2. The DC conductivity of undoped and doped polymers is measured in the temperature range of 300 -400 K and is found to increase with temperature. An increase in conductivity by five orders of magnitude has been observed after doping. Conduction mechanism was also studied in all of the samples. FT-IR (Fourier Transform Infrared spectroscopy) and Ultraviolet (UV)-Visible studies confirm the occurrence of PAni in conducting emeraldine salt form in the composites. The optical studies signify that absorption mechanism is due to direct allowed transition and the band gap decrease after doping. Thermal stability of all the composites has been explained on the basis of variation in Tc-Tg and ∆Hc by using DSC (Differential Scanning Calorimetery) measurements.
