SILVER NANOWIRE (AGNW) ELECTRODES ON PET SUBSTRATES FOR APPLICATION IN FLEXIBLE ELECTRONIC DEVICES

Tóm tắt

Currently, the demand for flexible electronic devices – capable of bending, such as TVs, smartphones, laptops, tablets, and solar cells – is rapidly increasing and has become an inevitable development trend, ushering in a new era in smart materials and device technology. One of the key factors determining the success of flexible optoelectronic devices is the fabrication of transparent conductive electrodes on flexible substrates. In this study, we successfully fabricated flexible, transparent, and conductive electrodes based on silver nanowires (AgNWs). This material shows great promise as a cost-effective and high-performance alternative to conventional ITO electrodes, offering excellent flexibility. The silver nanowires were synthesized using the polyol method, with an average diameter of approximately 50 nm and a length up to 50 µm, achieving an aspect ratio (length/diameter) of up to 1000 – highly favorable for flexible electronics applications. The resulting AgNW-based electrode film exhibited high optical transmittance (>80%) and a good figure of merit (104), comparable to traditional ITO electrodes on rigid substrates. Moreover, the electrode maintained stable optoelectronic performance after more than 800 bending cycles, clearly demonstrating its potential for next-generation flexible electronic devices.
