- •
Laser direct patterning of reduced GO was produced from 500 nm GO film on flexible (PET) substrate by femtosecond pulses.
- •
For thick LrGO film there is a minimum in resistance while linear crystalline quality increases with laser fluence.
- •
Laser induced embossing of GO provides 3D formation with details aspect ratio as 1:10.
- •
Two-step laser-induced detachment of GO patches from polymer substrates is shown.
