- Description
- Polyurethane (PU) is composed of polyisocyanate and polyol units joined through urethane linkages. The isocyanate and polyol units constitute different domains in PU, which are, in turn, responsible for its properties such as softness, flexibility, and hardness. Shielding of electromagnetic (EM) radiation is generally attained by reflecting EM waves from the surface, absorbing the signals, or by multiple internal reflections. Pristine PU is not an efficient electromagnetic interference (EMI) shielding material because of its nonconducting nature. But the EMI shielding can be improved by incorporating conducting polymers into the PU-based nanocomposite. Significant factors that influence the shielding effect of PU nanocomposites are the thickness and conductivity of the film. Features that predominantly influence the EMI shielding performance of nanocomposites are identified as the nanofillers used, the dispersion state, and the interaction between the filler and the polymer. This book chapter attempts to explain the EMI shielding of PU nanocomposites, synthesis of PU-based EMI shielding materials, different nanofillers used along with PU nanocomposites, and their efficiency in EMI shielding. 2026 Elsevier Ltd.
