Stretchable Water-Repellent PEDOT:PSS-Impregnated Polyurethane Nanofiber Mats for Electromagnetic Interference Shielding.

ABSTRACT: High-performance wearable textiles made from poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) hold great promise for electromagnetic interference (EMI) shielding in military and healthcare systems. However, achieving an optimal balance of resilience, flexibility, and electrical properties is challenging due to weak interfacial interactions between PEDOT:PSS and the host substrates. In this study, a robust and stretchable wearable textile fabricated via vacuum-assisted impregnation of PEDOT:PSS is presented onto an electrospun polyurethane (PU) nanofiber mat. The process creates a convoluted interlock network at the interface layer between PEDOT:PSS and PU nanofiber mat, enhanced by the large contact area, effective chemical interactions, and vacuum-induced pressure.
