| This aims to prepare multiwall carbon nanotubes / polymer nanocomposite stabilized by 1-butyl-3-methyl-imidazolium (BMIM)-surfactant. Dispersibility of MWCNTs in cellulose and natural rubber latex polymer matrix was studied and prepared via latex technology approaches by addition of 1-butyl-3-methyl-imidazolium (BMIM)- surfactant. The ability of BMIM-surfactants for dispersing MWCNTs in polymer was characterized using a range of techniques including field emission scanning electron microscopy (FESEM), thermogravimetric analysis (TGA) and small angle neutron scattering (SANS). And for-point probe measurements. Research finding showed that MWCNTs were more efficiently dispersed in cellulose utilizing 1-butyl-3 methylimidazolium- dodecyl benzene sulfonate (BMIM-DBS) than commercially available surfactant sodium dodecylbenzenesulfonate (SDBS). In conclusion, surfactant counterion gives an importance effect to improve the dispersibility of MWCNTs in cellulose. In implication, the results will provide the significant interest in improving properties of cellulose based nanocomposites. |
