Study on viscoelastic properties of phase-separated hydrogels by time-temperature superposition principle

conference paper

English

Time-temperature superposition principle has been utilized for the study on viscoelastic properties of phase-separated hydrogels. Hydrogels were prepared by interactions of biopolymers (negatively charged hyaluronan or positively charged diethylaminoethyl-dextran) with oppositely charged surface active agents (Septonex or Sodium dodecyl sulfate). By using the time-temperature superposition principle, the viscoelastic properties of these hydrogels have been studied over a large frequency range in comparison with routine macro-rheological approach. The results from time-temperature superposition principle are in good agreement with preliminary micro-rheological approach (dynamic light scattering technique).
