Abstract
A simple approach to fabricate graphene hybrid film consisted of Graphene/3-aminopropyltriethoxysilane (APTES)/polyethylene terephthalate (PET) is presented, using self-assembled monolayers (SAMs) for enhancement of conductivity. The SAMs of APTES was prepared on ultraviolet-ozone (UVO)-irradiated PET films via wet chemical technique. The density of APTES was saturated after UV treatment time of 1Â h for PET films; the carrier density and the optical transmittance were 9.3Â ÃÂ 10 12/cm2 and 82% for pristine graphene and 1.16Â ÃÂ 1013/cm2 and 86% for graphene hybrid films, respectively, and experienced at inflection point at 30Â min in UV treatment time. This behavior can be explained by surface morphology transition due to coalescence or clustering of mobile and low-molecular-weight oxidized components of PET.
