title: In-situ silica incorporated carboxymethyl tamarind: development and application of a novel hybrid nanocomposite.
abstract: A novel hybrid nanocomposite has been prepared using in situ incorporation of nano-sized filler (silica) onto carboxymethyl tamarind kernel polysaccharide (CMT). Various characterizations were employed to confirm that silica nano particles have been incorporated onto the polymer matrix. Rheological characteristics reveal stronger CMT-Si interaction at 0.5 and 1 wt% level. Beyond 1 wt% Si concentration, the interaction is less and so there is little drop in shear viscosity. Flocculation efficiency increases with incorporation of nano filler, maximum efficacy being observed at 1 wt% silica concentration. All the nanocomposites exhibited better flocculation characteristics in comparison to pure CMT.
