Conductive Cellulose Composites with Low Percolation Threshold for 3D Printed Electronics

Abstract We are reporting a 3D printable composite paste having strong thixotropic rheology. The composite has been designed and investigated with highly conductive silver nanowires. The optimized electrical percolation threshold from both simulation and experiment is shown from 0.7 vol. % of silver...
