Fig. 7. Confocal micrographs of a deionized suspension of hybrid silica/PNIPAM rods at 2 wt% (a) without electric field and (b) under an alternative electric field of E = 50 kV m−1 and f = 160 kHz. The white arrow gives the orientation of the electric field. Particles are dyed using MRB (methacryloxyethylthiocarbamoyl Rhodamine B).
