Abstract

POLYACRYLAMIDEs are water soluble macromolecules. These polymers are widely used for flocculation, separation and treatment of solid-liquid phase materials.In this research, organic-inorganic hybrid of POLYACRYLAMIDE/silica nanoparticle is prepared via radical polymerization. First, the SILICA NANOPARTICLE surfaces were modified by 3-methacryloxypropyltrimethoxysilane as coupling agent using a sol-gel technique in aqueous media in acidic condition. Afterwards, the modified nanoparticles are copolymerized by acrylamide monomer in presence of a peroxide initiator during a FREE RADICAL POLYMERIZATION. The chemical structure of the prepared modified nano-silica as well as POLYACRYLAMIDE nanocomposite was studied and confirmed by FTIR spectroscopy technique. The morphology of nanocomposite was investigated by scanning electron microscopy. The SEM micrograph showed that the surface of the composite did not display any phase separation. Nanoparticles distribution was investigated by SEM-EDX technique. The results showed a uniform distribution of particles throughout the polymer bulk. TEM analysis showed the presence of SILICA NANOPARTICLEs in bulk of polymer which is an indicative of suitable dispersion of nanoparticles. The THERMAL STABILITY of HYBRID NANOCOMPOSITE with that of POLYACRYLAMIDE was compared by TGA technique. The higher THERMAL STABILITY of HYBRID NANOCOMPOSITE with respect to homopolymer is indicative of a reaction between the modified nanoparticles and POLYACRYLAMIDE chain. The presence of silica particles in copolymer was also confirmed with EDX analysis in ash content of HYBRID NANOCOMPOSITE.
