Figure 5.

TEM images recorded for a 20% w/w PLMA₁₆–PBzMA₃₇ worm gel. Initially, worms are observed at 20 °C on dilution to 0.01% w/w solids [see image (A)]. On heating this 20% w/w gel to 90 °C, degelation occurs. Allowing the hot 20% w/w worm gel to cool from 90 to 20 °C (followed by dilution to 0.01% w/w solids prior to preparing a TEM grid) reveals mainly a worm phase [see image (B)], with a minor population of isolated spheres (see red arrows).
