Fig. 3. % Transmittance vs. temperature plots for (a) a 1.0% w/w solution of the PBeMA37 macro-CTA and (b) a 1.0% w/w dispersion of 32 nm PBeMA37–PBzMA100 spheres in mineral oil. The optical transmittance was monitored at a fixed wavelength of 650 nm on cooling from 50 °C to 20 °C (blue squares) and on heating from 20 °C to 50 °C (red circles), with 5 min being allowed for equilibration at each temperature. Solid lines are shown as a guide to the eye.
