Improvement of the Red Mud Polymer-Matrix Composites by Organophillization of Red Mud


Article Preview

Red mud was organophilized by aniline formaldehyde and to know the effect of various filler loading on the properties of PVA-Organophilized red mud composite prepared by a conventional solvent casting technique and comparison of the same with that of the virgin polymer, various characterizations was done. The as-synthesized composite films were typically characterized by FTIR spectroscopy and X-Ray Diffraction.The exfoliation of galleries of organo- red mud was more evident in the composite film containing 2% of filler loading.The morphological image of the composite materials was studied by scanning electron microscopy (SEM) and optical microscope (OM). The thermal properties measured by thermogravimetric analysis (TGA) showed that organored mud enhanced the thermal stability of a series of composite materials freestanding films.The differential scanning calorimetry (DSC) showed increase in glass transition temperature and crystallization of the composite films.
