▎ 摘　　要

To improve the joining strength and electrical conductivity, this study aims to develop an ultraviolet (UV) laser annealing to join AgNWs coated on polyethyene terephthalate substrates. The developed graphene/AgNWsbased strain sensors with UV laser-ablated electrodes were highly promising for in situ structural health monitoring of wind turbine blades. After the UV laser annealing, the rate of resistance changes of laser-annealed AgNWs had a minimum value of-2.92 +/- 1.0 % when the laser power set at 0.4 W. Moreover, the sheet resistances of laser-ablated graphene/AgNWs films increased with increasing the laser areal fluences. The laser areal fluence of 10.88 J/cm(2), pulse repetition frequency of 200 kHz, scan velocity of 400 mm/s, and line scan pitch of 0.02 mm were used to ablate the graphene/AgNWs electrode structure of strain sensors. During the bending test, the graphene/AgNWs-based strain sensors with an electrode width of 0.1 mm had the largest gauge factor of 13.47. Furthermore, the graphene/AgNWs-based strain sensors demonstrated an excellent response and recovery during the real-time bending test of wind turbine blades.
