N2 - Pluronic PE9400/water binary systems at different concentrations were characterized by means of rheological and microstructural techniques. Temperature ramps revealed a structural transition defined by three zones, which determine time-dependent behaviors. Thus, non-time-dependent, antithixotropic, and thixotropic behaviors were observed depending on Pluronic’s concentration and temperature. These phenomena were analyzed resorting to rheological tools, namely hysteresis loops and transient tests, and supported by Cryo-SEM. The results obtained demonstrated the shear-sensitive character of these systems. All properties presented by these systems make them adequate and interesting for many applications such as injectable systems for tissue repair.
