Effects of Synthesis Temperature and TEMED Concentration on the Swelling Behavior of PAAm Gel

Abstract

The authors have investigated the swelling behaviors of several P AAm hydro gels which are synthesized at several temperatures and with some concentrations of N,N,N ,N-tetramethylethylendiamine (TEMED), because the gels' swelling degrees are deeply related to their network structures determined by the reaction fashions in their synthesis processes and because the heavy metal adsorption functionalities of their ionized homologues, which is important for the application for purifying environments, seem affected considerably by the swelling ratios. By the investigation in the present study, it has been revealed that the swelling degree of the P AAm gel in these conditions have received considerable effects by the TEMED concentration and synthesis temperature.
