Abstract:
Icing on significant equipment， such as airplane wings， wind turbines， and solar panels， causes aerodynamic changes and important component deformation， which seriously threatens operation safety. However， fabricating flexible， conformal， and robust photothermal de-icing surfaces remains challenging. Herein， a porous and hydrophobic laser induced graphene （LIG） based photothermal anti-frosting/de-icing surface is designed and fabricated by direct laser writing technologies. The LIG film is prepared by laser irradiation on polyimide （PI） film. After laser irradiation， the LIG film exhibits porous structures and a high C/O ratio. Due to the existence of porous structures and a high C/O ratio， the LIG film shows hydrophobic properties （CA， ~123.2°）， high absorption， and good photothermal conversion. Thus， the LIG film displays photothermal anti-frosting and de-icing abilities. The work shows great potential in developing flexible， conformal， and robust photothermal anti-frosting/de-icing surfaces.
