Abstract Scope |
Conductive polymer composites (CPCs) fabricated by mixing conductive filler and insulated polymer are widely used in flexible piezoresistive pressure sensors. However, the percolation theory shows that in order to form a conductive path between the fillers, a high volume fraction of fillers is required, which gives rise to filler aggregation problem, low transparency properties, and high cost. We use silver nanowires (AgNWs) and silicone to fabricate conductive polymer composites. By controlling the orientation and movement of AgNWs through an external electric field, we found that the closely connected AgNWs showed a dendritic structure instead of randomly distributed. This dendritic structure has shown superiority in terms of an ultra-low percolation threshold. |
