Abstract
The composites of properties of ethylene-propylene-diene-monomer (E) and acrylonitrile butadiene-rubber (N) composites of
graphene oxide (GO) and reduced graphene oxide (G) were prepared by a combination of solution and open-roll method.
They include single matrices (EGO and EG) and blends N/E, 20 part of hundreds of rubber (phr)/80 phr (A), 80 phr/20 phr
(B), and 50 phr/50 phr(C) blend containing GO and G. The physico-mechanical properties including vulcanization, tensile,
glass transition temperature (Tg), and dielectric spectroscopic properties were evaluated. The N-rich systems reinforced with
GO, cured faster than the E-rich systems. Also, N-rich systems obtained the highest dielectric constant ðɛ′Þ, especially when
GO and G were incorporated, for example, NG and N-GO obtained 317 and 283% increment in ɛ′ than EG and EGO,
respectively. In terms of tensile properties, AGO exhibited the highest strength and elongation at break properties (%).
Therefore, solution mixing technique of rubber blends filled with nanoinclusion can be achieved with the tendency of reducing
cost without the use of compatibilizer and still maintain the integrity of the physical properties of the final product. The result
obtained therefore shows that the current compositions can find various applications in oil/gas sealants, heat-resistant
applications, and energy storage materials with minimal losses.
