Templated synthesis of 1D Ag nanohybrid in the solid state and its organized network for strain-sensing application

Abstract

1-dimensional silver (1D Ag) nanomaterial with organized structure has shown versatile applications in electronic skin, energy storage and catalyst, etc. However, conventional fabrication methods usually suffered from various drawbacks, such as not being environment-friendly, tedious preparation process, time- and energy-consuming. Herein, we propose a simple and green strategy to produce 1D Ag nanohybrid using cellulose nanocrystals as template. The templated 1D Ag nanohybrid presented amphiphilic character and excellent water dispersibility, which enabled it to form an organized interconnected conductive network through self-assembly in rubber latex. The obtained composite material showed dramatically enhanced electric conductivity and very low percolation threshold. Importantly, this assembled conductive network exhibited extremely high sensitivity under stretching with a gauge factor up to ~304 and outstanding durability which could endure more than 10 000 cycles of bending. The resulted strain sensor could be used to detect both small- and large-scale human motions, such as facial expression, coughing, gesture language and limb movements. We anticipate that this templated 1D Ag nanohybrid and its assembled organized network will find applications in flexible strain sensors, electromagnetic shielding materials, artificial muscle actuators and other electronic devices.
