摘要：Gold nanowires (AuNWs) exhibit significant promise for formulating water-based conductive inks due to their high conductivity, robust chemical/mechanical stability and eco-friendliness. However, the fundamental mechanisms governing AuNW adsorption onto substrate surfaces remain poorly understood, presenting constraints for their practical implementation in ink formulation. Here we elucidate the underpinning of AuNW adsorption onto cotton fibers. Our experiments and mechanistic analysis indicate that AuNW adsorption onto cotton fibers occurs via multilayered deposition, exhibiting close alignment with Freundlich isotherm model. Based on understandings, we engineer a highly flexible and sensitive pressure sensor by simply using AuNWsdyed cotton fibers as compliant conductive resilient fillers. Our findings not only advances fundamental understanding of nanomaterial adsorption beviour on cellulosic materials, but also establishes a straightforward methodology for developing water-based conductive inks.
