The plasma-polymerized-fluorocarbon (PPFC) thin film has an amorphous structure and exhibits very high transparency and flexible properties. In particular, PPFC thin films deposited using a mixed target of carbon nanotubes (CNTs)−Polytetrafluoroethylene (PTFE) display a very low refractive index of 1.38, as well as a hydrophobic surface that imparts the self-cleaning. In this study, the optical and surface properties of nanostructured-PET and PPFC/nanostructured-PET films were investigated. By depositing the PPFC on a nanostructured polyethylene terephthalate (PET) surface, the antireflection effect increases due to the low refractive index of PPFC and gradient refractive index of nanostructure. As a result, the reflectance of PPFC/nanostructured PET decreased by 56% from 9.1% (the reflectance of original PET) to 4.2% at a wavelength of 550 nm. |
