Abstract

This project aims to explore the excellent properties of graphene and other two - dimensional materials (graphene oxide - GO, reduced graphene oxide - rGO, molybdenum disulfide- MoS2 and hexagonal boron nitride - hBN) to produce polymer nanocomposites that meet the needs of the different areas of application (filaments, films and injected pieces). In addition to the production and characterization of nanocomposites, this project has as its main focus the study of the mechanisms of degradation and stabilization of these materials, something that until now has not been explored. The degradation / stabilization study will focus on the correct choice of processing additives and protectors against UV radiation. The choice of the polymer matrices was correlated with these areas, such as: polypropylene - PP, low density polyethylene - LDPE and poly (butylene adipate-co-terephthalate) - PBAT for films and injected pieces, and poly(ethylene terephthalate) - PET for filaments. The project comprises two steps: (1) Production and characterization of polymeric nanocomposites based on two-dimensional materials; (2) Study of stabilization of polymeric nanocomposites based on two-dimensional materials. The success of this project depends fundamentally on the production of two-dimensional materials and the strategies of insertion of these materials into the polymer matrices. In order to reach the goals of this project, a multidisciplinary team of researchers was set up with researchers from Graphene and Nano-Material Research Center - MackGraphe, and national (Institute of Macromolecules - IMA/UFRJ) and international collaborations (Case Western Reserve University - USA).
