Urea Uptake and Release by Novel Macrogels from Dimethylacrylamide

Nahit AKTAŞ

A novel macrogels poly(N,N-Dimethylacrylamide) (p(DMAAm)) and its derivatives were synthesized from DMAAm for use in urea uptake and release. p(DMAAm) surface was modified by NaOH and HCl to obtain p(DMAAm)/NaOH and p(DMAAm)/HCl, which are negatively and positively charged, respectively. The dynamic swelling behaviors, water retention and pH sensitivities of the macrogels were studied. It was found that all macrogels exhibited the equilibrium swelling ratio (SR) in the range 1068-1451%. Swelling kinetics showed that the macrogels possessed Fickian diffusion behavior while the diffusion coeffic ...More
