Abstract

Graphene obtained by Chemical Vapor Deposition (CVD) is the most appropriate one to industrial scale applications, since samples with dimensions on the order of centimeters are easily obtained. After the production of graphene, its transference is needed to the varied applications. Many techniques have been developed for that, but the only one to provide defect-free graphene (such as cracks and/or wrinkles) excluding the chemical attack step is the "Direct Dry Transfer - DDT". This project aims to understanding the graphene-polymer interface phenomena that rule the transfer process by a further study which evaluate these phenomena, thereby allowing the mastery of the technique. The project will utilize the infrastructure of the SPEC project "Graphene: photonics and optic-electronics" (2012/50259-8) and also of the Regular Project (2014/22840-3) entitled "Direct dry transfer of CVD-graphene to bidimensional and tridimensional polymeric substrates" as a basis for execution of project activities. The evaluation of the graphene-polymer interface phenomena will be executed by a controlled experimental methodology, with measures of contact angles and AFM and polymer oscillatory rheological tests, analyzing the results in a way to improve the DDT technique.
