Abstract

Multiwalled carbon nanotube (MWCNT) reinforced chlorobutyl elastomer nanocomposites were prepared. The morphology of nanocomposite samples has been studied from scanning electron microscopy (SEM). The effect of MWCNT loadings on mechanical properties shows increase in tensile strength, hardness, and modulus and decrease in elongation at break with MWCNT loadings, which can be attributed toward better chlorobutyl-MWCNT interaction. At higher filler loading, the rate of increase slowly decreases. The above explanation was also verified from bound rubber (BdR) measurements, showing increase in BdR contents with MWCNT loading. Swelling of the nanocomposites in chloroform, benzene, and trichloroethylene was measured and found to be dependent on both MWCNT concentration and the type of solvent used. The degree of swelling, diffusion coefficient, and penetration rate was calculated. The effect of solvent on swelling properties at different periods of time shows that the degree of swelling increases with time and decreases with concentration of MWCNT loading. Dynamic mechanical properties of nanocomposites have been studied as a function of temperature (from -100°C to 100°C) at a constant frequency of 1 Hz and 1% strain. The effect of MWCNT loading on storage modulus, loss modulus, and loss tangent has been studied. The nonlinearity in tan δ and storage modulus and loss modulus was explained on the basis of MWCNT-elastomer interaction. The smooth Cole-Cole plots explain the nonlinearity in the nanocomposites as well as good distribution of MWCNT in the elastomer matrix.
