Dynamic mechanical analysis and topological studies of phenoxy reinforced with modified red mud waste nanofiller based composites

Roughness on pristine and aged or polymer composite surfaces is of enormous practical importance for polymer applications. This study is about the comparison of the response of a red mud based composite material to an oscillatory deformation (here in tension–torsion mode) as a function of temperature. This study deals with the use of varying quantity of modified red mud as a nanofiller in a poly(hydroxy ether) of bisphenol A (Phe) based matrix. Poly(hydroxy ether of bisphenol A) (Phe) based polymer nanocomposites reinforced with a layered red mud with acidic and organic modifications were prepared by conventional solvent casting technique. The best dispersion occurred in the polymer nanocomposites where the interactions between the functional groups of the polymer matrix and those of the organic substitution of the red mud appeared to be the highest. The oscillatory response was characterized by dynamic mechanical analysis. The roughness and interfacial adhesion in the as synthesized composite materials was analyzed by atomic force microscopy. The dispersion and particle size of the filler materials in composite materials was studied by transmission electron microscopy.
