Mechanically robust conductive carbon clusters confined ethylene methyl acrylate-based flexible composites for superior shielding effectiveness

Arresting of conducting carbon black into polymeric matrix to develop flexible and light weight composite has been a widely practiced platform. Extensive development of telecommunication creates a major vexations regarding radiation pollution. Thereafter, we have been motivated to develop low-cost, flexible composites of specialty carbon black VXC (Vulcan XC 72)-filled ethylene methyl acrylate (EMA) by mechanical mixing technique. Developed composite has significant conductivity (6.67x10(-4)Scm(-1)) with promising mechanical and thermal properties. Dispersion of high-structured carbon blacks in EMA was investigated by small angle X-ray scattering to reflect the dependency of conducting mesh formation on dispersion. Interconnected filler network development has been visualized by field emission scanning electron microscope and high-resolution transmission electron microscope. Electromagnetic interference shielding value in the X band has calculated to be 30.8dB. Such features can make this EVXC (EMA-Vulcan XC 72) composite a useful alternate for flexible electromagnetic interference shielding material.
