dc.description.abstract The rheological behavior of Dibenzylidene D-Sorbitol (DBS) gels formed in ethylene glycol, glycerol, mineral oil, ethanol, and chlorobenzene was studied using oscillatory squeezing flow viscometry. The storage (G ′) and loss (G ″) moduli were measured as a function of gellant concentration (0.5-2 w-w) and type of solvent. As expected greater values of gel strength (G ′) were observed for gels containing higher concentrations of DBS. In addition, both storage and loss moduli of 2percent systems were mostly frequency independent over the studied range, whereas 0.5percent gels did exhibit some degree of dependence. We also found that the solvent plays an important role in the properties of the gels. Among the parameters that affect the viscoelastic properties of DBS gels, the solvent polarity and its ability to form hydrogen bonding may have significant effects on the gel rheology. © 2011 Springer-Verlag.
