Silver Nanowire :

Silver nanowire has potential applications on transparent conducting film and electrode of electrochemical capacitor due to its excellent conductivity. Transparent conducting film (G-film) was prepared by coating silver nanowires on glass substrate using Meyer rod method, which exhibited better performance than carbon nanotube and graphene. The conductivity of G-film can be improved by increasing sintering temperature. Electrode of electrochemical capacitor (I-film) was fabricated through the same method with G-film on indium tin oxide (ITO). CV curves of I-film under different scanning rates had obvious redox peaks, which indicated that I-film exhibited excellent electrochemical pseudocapacitance performance and good reversibility during charge/discharge process. In addition, the specific capacitance of I-film was measured by galvanostatic charge/discharge experiments, indicating that I-film exhibits high special capacitance and excellent electrochemical stability.

Silver nanowire application:

1.silver nanomaterial become the focus of research because of their unique physical and chemical properties, which has been widely used in catalysis, optical, electrical, and antibacterial areas. Among these various silver nano structures, nanowire has attracted intense forces due to its high dc conductivity and optical transmittance.

2.Due to the optoelectronic devices become smaller and lighter, there is an increasing need for efficient transparent electrodes, silver nanowire can be used as a replacement of ITO in the future.

3.silver nanowire can also be used as electrodes of electrochemical capacitor. Transparent capacitors have potential application on energy storage.

4. silver nanowire can be oxidized to Ag2O forming Ag/Ag2O core-shell nano structures during the electrochemical process, therefore, silver nanowire is a promising candidate of electrochemical capacitor.
