✦ Synopsis

the gap width was 500 mm). All viscoelastic measurements were performed at (25 AE 0.1) 8C. Dynamic viscoelastic measurements were performed with the range of the oscillatory angular frequency, w = 10 À1 -100 rad s À1 and with the strain, g = 0.05 to ensure the linear viscoelasticity behavior, except for the stress dependence measurements.

To determine G' and G'' versus the reconstitution time, the organogel based on 1 was initially disintegrated for 10 min by using a mechanized vibrator (vortex) operating at 60 Hz and 2600 rpm. The disintegrated gel was immediately put on the rheometer and the time evolution experiment was performed.
