Rheological investigation of the viscoelastic thixotropic behavior of synthesized polyethylene glycol-modified polyacrylamide hydrogels using different accelerators

The present work is mainly focused on the synthesis and comprehensive rheological investigation of uniform and large macroporous polyethylene glycol-modified polyacrylamide hydrogels [PEG-m-P(AAm)] through free radical polymerization using different accelerators (ascorbic acid (AsA), thermal activation (60 °C) and N,N′,N″,N‴-tetramethyl ethylenediamine (TEMED)). The synthesis and surface morphology of the hydrogels were confirmed by FTIR and SEM...
