Herein, a superhydrophobic and highly conductive cotton fabric (CF) composite with outstanding corrosion resistance for wearable textile electronics is developed. The fabrication process of the fabric composite involves spraying deposition and electrodeposition. Ag nanoparticles (AgNPs) are first synthesized on cotton fibers surface via two components spraying, forming cotton fibers core/AgNPs shell structure. The CF/AgNPs composite is then covered with a layer of cerium myristate (CeM) by electrodeposition, which endows the composite with superhydrophobicity and outstanding corrosion resistance. The resistivity of CF/AgNPs/CeM composite could reach as low as 0.106 Ω mm. Moreover, the obtained CF/AgNPs/CeM composite exhibits excellent self‐cleaning property and superhydrophobicity with a contact angle (CA) of 158.4°. Also, it maintains superhydrophobicity (CA > 150°) after 60 cm abrasion test or immersion in strong acidic/alkaline solution (pH = 1 or 13) for 24 h. In addition, the corrosion current density of conductive fabric composite (CFC) after electrodeposition decreases to 4.79% of the original value in simulated sweat corrosive media, suggesting a significant improvement of anti‐corrosion. The developed superhydrophobic CFC with excellent corrosion resistance and self‐cleaning performance has promising applications for wearable electronics in harsh conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
