| 초록 | Nanocomposites consisting of Styrene Butadiene Rubber (SBR) reinforced with the exfoliated graphite (EG) and untreated graphite (UG) with concentrations of 6wt% were fabricated. Processing techniques such as acid-treatment, thermal shock, sonication were employed in the fabrication of EG. The EG oxidized using sulfuric and nitric acids were analyzed by the Raman scattering, Fourier transformed infrared spectroscopy (FT-IR) and X-ray diffraction (XRD). The FT-IR results indicate the presence of acid groups in the treated samples, and Raman spectroscopy of EG further corroborate the formation of surface defect due to the introduction of carboxyl groups. However, the structure of XRD peaks did not change irrespective of processing techniques. The SBR-based nanocomposites were characterized using the scanning electron microscopy (SEM), electrical and thermal conductivity measurement and tensile properties and fatigue properties measurements. The storage modulus and glass transition temperature (Tg) of the composites are determined using Dynamic Material Testing System (DMTS). The results showed that nanocomposites onto EG enhanced mechanical properties and fatigue properties of nanocomposites compared to those containing UG due to increase the interaction between the polymer and the EG. And the dynamic properties of nanocomposites had no influence according to the processing techniques. |
