Clay nanocomposites

The objectives of this research work are: Study the clay intercalation by organic dye and develop a process to produce nanoclay-dye pigment with better stability and good performance; Conduct structural characterization to verify the level of intercalation and stability of clay-dye pigment by using X-Ray diffraction (XRD) and Transmission Electron Microscopy (TEM); Investigate the thermal stability of clay dye pigment using Thermo Gravimetric Analysis (TGA) to reveal the effect of dye intercalation into the clay on improving thermal stability of organic dye; Compound the clay- pigment with ...

Polypropylene/ maleic anhydride /organic montmorillonite nanocomposites (PP/ MA/ Org-MMT) have been prepared via direct melt intercalation in an internal mixer. Maleic anhydride (MA) was used as a compatibilizer to improve the dispersability of the clay. The structures of nanocomposites have been characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Mechanical properties and thermal stability were determined by tensile analysis and thermogravimetric analysis (TGA), respectively.
