Study on the Relaxation Behaviour of Hydrogel Materials Using Classical Rheology Methods
Original language description
Proposed paper investigates relaxation behaviour of hydrogel materials using classical rheology methods as a part of the complex rheological characterization of these systems. Specifically, creep and recovery tests as well as three interval thixotropy tests were studied in this paper. Extensive optimization of these tests was carried out in order to find ideal measurement settings, which for creep tests consist in proper values of applied stress, temperature and duration of loading and relaxation step. the essential variables for three interval thixotropy tests are frequency of oscillation, temperature and applied strain as well as duration for each step. the optimization procedure was performed using 1 wt. % physically crosslinked agarose hydrogel and the tuned tests were applied besides other different concentrations of agarose hydrogel also to hyaluronic acid based hydrogels formed due to interactions between negatively charged polyelectrolyte groups with positively charged surfactants and to po
