“…Therefore, the graphene/AgNW/graphene TCF possesses electronic characteristics of bilayer graphene. In addition, as for the graphene/AgNW/graphene TCF, I 2D /I G ratio in the Raman spectra decreases from 2.7 to 1.6 because of the change in electron bands by interactions of AgNW and graphene [33]. These results clearly confirm that the CVD-grown graphene was clearly and successfully transferred onto the AgNW/ graphene TCF, leading to the sandwich-structure of the graphene/AgNW/graphene TCF.…”

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.

“…In the case of silver, well-conducting NW arrays were produced by applying mechanical pressure, [19][20][21] by thermal, 17,22-26 nanoplasmonic 11,27 or Joule 28 annealing. [34][35][36][37] Most of these strategies are time-and energy-consuming, involve special complex equipment and exotic nanomaterials.

The surfactant polyvinylpyrrolidone (PVP) commonly used to synthesize silver nanowires (AgNW) in solution is known to negatively affect the performance of nanowire-based thin film electrodes. An insulating shell of the polymer hinders tight contact between the nanowires themselves and between the nanowires and substrate, resulting in high sheet resistance of the freshly prepared nanowire films. Here, we develop a simple low-temperature method allowing us to reduce the sheet resistance of AgNW networks and simultaneously improving the optical transmittance. The method is based on the capacity of PVP to absorb moisture which results in a strong decrease in the glass transition temperature of the polymer.The latter leads to softening effects, causing a reduced wire contact resistance already at 60 C for 90 nm thick AgNWs and even at 45 C for 35 nm thick AgNWs. As a result, the sheet resistances of the thin film electrodes treated by our method are near to the values conventionally obtained after thermal annealing at temperatures between 140-250 C. Our humidity assisted low temperature approach is especially advantageous for organic electronics and fabricating devices on thermally sensitive transparent flexible foils. † Electronic supplementary information (ESI) available: Changes in total transmittance DT vs. initial total transmittance; transmittance spectra of NW-35 electrode vs. annealing time; SEM images of a NW-35 electrode on glass; sheet resistance vs. annealing time at a constant temperature of 60 C and different RH values; SEM image, transmittance and reectance spectra of NW-90 electrode on PEN foil.
