The high-quality flexible graphene thin films have been fabricated by the nondestructive rubbing method. The film exhibits an excellent photothermal conversion ability after oxygen plasma treatment and multiple mechanical bending. The temperature can be increased to 47.4°C even under a low laser irradiation power of 240mW with a decent heating rate of 0.3°C/s, and photothermal conversion efficiency reaches as high as 28%. The steady-state temperature can be precisely tuned by changing the laser power. These excellent results indicate graphene-based photothermal elements holding great promise for practical applications
