Abstract :

Polyacrylamide hydrogels were synthesized by free radical polymerization of various acrylamide cross linker ratios at room temperature using BZ mixture in place of conventional initiators and accelerators. FTIR spectroscopy was used to characterize the polymer. The reaction between monomer and cross linker results in the formation of 3D polymer gels. Rheological studies were done to study the change in viscosity with the change in monomer cross linker ratios. Both elastic modulus (G`) and viscous modulus (G``) are measured for the prepared polymer gels between parallel rheometer plates. The elastic modulus remains constant with frequency and is significantly larger than viscous modulus. Effect of temperature on the polymer gels was studied. Bromate being the main radical initiator in the BZ mixture. Effect of its concentration on the viscosity of one of the polymer gel was considered.
