Dispersion, Mechanical, thermal, viscoelastic and dielectric properties of nano graphite platelets/flouroelastomer composites |
| 초록 |
The potential of exfoliated graphite nano platelets(xGnP™) as reinforcing fillers in flouroelastomer has been investigated. The dispersion of the nano graphite platelets in the polymer matrix has been investigated by WAXD, SEM and TEM. WAXD studies indicated that the processing of composites did not change the inter-gallery distance (d-spacing) of the graphite platelets. Formation of weld lines on the fracture surface of the composite has been observed by SEM and optical microscopy. The thermal stability was determined using thermogravimetric analysis. The composites showed higher thermal stability in comparison with unreinforced polymer Dynamic mechanical analysis and dielectric relaxation spectra were used to study their relaxation behavior as a function of temperature and frequency. |
