Resumo
The application of a composite material of pseudoboehmite, polystyrene
and graphene oxide was studied. The present work is the synthesis and characterization
of high-impact polystyrene (HIPS) nanocomposite, with pseudoboehmite
(PSB) and graphene oxide. Pseudoboehmite particles with nanometric dimensions
were obtained by sol-gel process. The composites were characterized by mechanical
tests (tensile strength, flexural strength, Izod Impact, Shore D Hardness), thermal
(Flow index, temperature of thermal deflection under load-HDT, Vicat softening
temperature, differential tests thermal analyses and thermogravimetric analysis) and
morphologically by Scanning Electron Microscopy (SEM). The results obtained
were compared with HIPS matrix properties, without PSB and graphene oxide addition.
From the thermal analyzes, composite samples showed higher decomposition
temperatures compared to pure high-impact polystyrene especially in the thermogravimetric
analysis results, showing a considerable increase in the temperature at
which material decomposition begins (322 °C for pure high-impact polystyrene and
380 °C for the composite).
