Abstract

Wearable electronic devices require novel hybrid polymer composites that offer flexible, lightweight and highly effective EMI shielding characteristics. The development and characterization of flexible polymer composites combining hard magnetic nanoparticles and electrically conductive fillers are explored. The suitability of thermoplastic polyurethane (TPU), polydimethylsiloxane (PDMS) and epoxy resins for use as EMI shielding composite matrices was evaluated in terms of their flexibility, stability and biocompatibility. Hybrid filler systems were developed to boost shielding effectiveness by combining both loss mechanisms, as well as their contribution to mechanical flexibility and conformability. Several methods such as solution blending, in-situ polymerization and layer-by-layer assembly were used to maximize the uniformity of the filler distribution and improve the interfaces between the nanofillers and the polymer matrix. The composed materials were characterized based on electrical conductivity, tensile strength, thermogravimetric properties and Raman spectroscopy. The hybrid composites exhibited shielding effectiveness greater than 40 dB throughout the frequency range of 2 to 18 GHz while maintaining strong mechanical performance under repeated Load. The composite achieved remarkable strength and mechanical extensibility, making it suitable for use in wearable devices. The hybrid CNF/rGO composites displayed good biocompatibility and a surface that was compatible with direct skin contact. This research demonstrates the promising applications of hybrid polymer nanocomposites as cutting-edge EMI shielding materials in flexible electronics, sensors and smart textiles.

Keywords: Electromagnetic interference shielding, Hybrid polymer composites, Reduced graphene oxide (RGO), flexible electronics, nanofiller dispersion, wearable materials.
