Advances in modern electronics require more robust and versatile functional components. We combine commercially available paraffin wax–polyolefin (PF) thermoplastic (elastomer matrix binder) with bulk-produced carbon nanofibers (CNF, charge percolation network for electron transport, imparting nanoscale roughness) to fabricate adherent thin-film composite electrodes. The simple wet-based process produces composite films capable of sustained ultra-high strain (500%) with resilient electrical performance (resistances of the order of 101–102 Ω sq-1). The composites are superhydrophobic for long-term corrosion protection, maintaining extreme liquid repellency at severe strain. Comprised of inexpensive common materials applied in a single step, the present scalable approach eliminates manufacturing obstacles for commercially viable wearable electronics, flexible power storage devices and corrosion-resistant circuits.
