# Effects of Intrinsic Factors on the Stability of Silver Nanowire-Based Flexible Electrodes
## 4 Conclusions  
The differences in the stability of AgNW electrodes under the conditions of different flexible substrates, surface densities of AgNPsWs, and surface modification of AgNPsWs, which are the intrinsic parameters of the electrodes, are comparatively investigated, and the reasons and mechanisms of action that cause these differences are explored. The results of the study show that silver nanowire electrodes have a large specific surface area and high chemical activity, and silver nanowire electrodes with untreated and unprotected surfaces produce a large number of nanoparticles and broken wires on their surfaces under the action of external high temperatures and high-intensity light. There is both chemical and physical damage on the surface of silver nanowires, which leads to the rapid deterioration of electrode performance. The thermal and light stability of the silver nanowire electrodes can be significantly improved by introducing a flexible substrate PVA with encapsulation, appropriately increasing the surface density of the silver nanowires, and modifying and curing graphene oxide on the surface of the silver nanowires and the connection junctions. The reason is that the introduction of the above structure can play a protective role for the surface of the silver nanowires and the nanowire connection junctions, so that the surface of the silver nanowires and the silver nanowire connection junctions are not directly exposed to the external environment, thus effectively inhibiting the generation of nanoparticles and fractures on the surfaces of the silver nanowires. The surface modification of GO is the modification of the atomic layer, which can not only improve the electrical conductivity of the nanowire junction and reduce the contact resistance of the junction through its large \(\Pi\)-bonds, but also effectively block the external atmosphere, light, and temperature damage to the electrode surface, and improve the stability of the electrode. To realize adequate and uniform coverage of GO on the surface of silver nanowires, it is necessary to adopt and develop GO atomic deposition technology to realize adequate protection of the surface of silver nanowire electrodes.
