Formation of uniform reduced graphene oxide films on modified PET substrates using drop-casting method

- Drop-casting method was used to prepare reduced graphene oxide transparent and conductive films.
- Four types of PET substrates with or without modification were investigated.
- Uniform and continuous RGO films were deposited on polydopamine-coated PET substrate.
- The prepared RGO film exhibited a sheet resistance of 21.75 kΩ/sq at 82% transmittance.
