Oxidation was a man issue for the silver-nanowire electrodes when the bulk silver reduces to nano-scale size, restricting it to practical application due to the significant rise of sheet resistance. We reported a simple method by virtue of incorporating polyethoxysiloxane (PES) into silver-nanowire layer to enhance the resistance to oxidation and thermal shock. As a result of the PES incorporation, the temperatures for oxidation to occur were raised from 250 and 300℃ to 300 and 500℃ under air and N 2 atmospheres, respectively. Moreover, after the PES incorporation the silver nanowires became tighter contact in cross connection due to the sol-gel shrinkage, resulting in a near 2-fold enhancement in the conductivity and superior bend performance compared to the pristine AgNWs electrodes. We used the silver-nanowire electrodes incorporated with PES to prepare the G/F/F-stack dual-touch sensor, revealing a rapid response and stable performances more than 3 months.
