Dynamic mechanical and thermal properties of nitrile rubber/montmorillonite clay nanocomposite |
| 초록 |
The nitrile rubber/unmodified montmorillonite clay nanocomposite was prepared by latex blending method followed by melt mixing of compounding ingredients using two roll mill. The X-ray diffraction(XRD) studies showed the formation of intercalated/exfoliated structure of clay in the rubber matrix. The transmission electron microscopy(TEM) augmented the XRD finding by showing the intercalated/exfoliated morphology of clay platelets. The dynamic mechanical analysis showed increase in storage modulus of clay filled nanocomposites at all the temperature ranges due to the confinement of polymer chains between the clay layers. Nanocomposites showed a decrease in tan δmax peak height with a shift towards higher temperature indicating the reduction in the segmental mobility of polymer chain. The thermogravimetric analysis indicated the improvement in the thermal stability of nitrile rubber/clay nanocomposite. |
