🧪 Carbopol in glycerin, temperature series (community)

dataset id: caggioni_carbopol_glycerin_temp

Equilibrium flow curves of Carbopol in glycerin: 51 points each from 0.001 to 100 s^-1 at 20, 30 and 40 C. The temperature series lets the background viscosity be extracted from TC-model fits and tested against the solvent’s Arrhenius law: the fitted background viscosity follows Arrhenius behavior with an activation energy close to literature glycerol. A fourth sweep at 50 C was dropped from the curated set. Originally measured for the rheofit Carbopol-in-glycerin walkthrough.
