Research On Embedded Flexible Conductors Based On Silver Nanowire

The production of flexible electronic systems includes stretchable electrical interconnections and flexible electronic components,which promotes the research and development of flexible conductors and stretchable conductive materials with large deformation,bending resistance,and torsion resistance.Silver nanowire networks have advantages in the development of flexible electronic products due to their high conductivity,good transparency,and resistance to bending.Selecting silver nanowires as conductive carriers for research.Silver nanowires were synthesized using alcohol reduction method,and the effects of different preparation parameters on the morphology of silver nanowire products were studied.Finally,a simple circuit conduction was achieved using silver nanowire ethanol solution.The specific contents are as follows:（1）Silver nanowires with an average length of about 10μm and diameter of about 46 nm were synthesized using alcohol reduction method.To determine the optimal reaction parameters for synthesis,the effects of different temperatures,types of PVP,different ionic auxiliary salts,and the rate of dropping Ag NO₃ solution on silver nanowire products were explored.By improving the preparation and treatment methods before and after the reaction,high yield silver nanowires were obtained,and the resistance value was reduced by more than 10000 times compared to the initial product.Determine 170℃as the most suitable reaction temperature,use PVP 360and Na Cl as coating agents and ionic aids,and add Ag NO₃ solution dropwise at a rate of 2 ml/min.（2）Acrylate film was prepared using CN 9021NS as the main raw material,with a tensile rate of over 400%.A silver nanowire coating was prepared on acrylic film using an ethanol suspension prepared with silver nanowires,with a resistance value of4.9Ω.A 1.5V battery powered bulb circuit was built using it,demonstrating its practical conductivity.
