Shielding Efficacy of Polymeric Nano-Structure

In recent decades, polymers have gained superior eminence owing to range of applications. Their range of applications covers a broad spectrum including energy storage, anticorrosive materials, sensors, electromagnetic electrostatic charge dissipation, electromagnetic interference (EMI) shielding, organic light emitting diodes, photovoltaic, and catalyst supporting material. The EMI shielding and microwave absorption properties of polymers can be elucidated in terms of electrical conductivity and presence of localized charges escorting strong polarization and relaxation effects. Electromagnetic interference shielding fits to the class of intelligent packaging. EMI is an undesirable electromagnetic induction provoked by extensive use of alternating current or voltage inducing signals in nearby electronic circuit. The interference may bring about human health effects. The varieties of details are covered relative to polymer nano-structured nanocomposites.
