Figure 5

Manipulation of polymer‐dispersed liquid crystals under SAW excitation. The left panel shows a schematic depiction of the experimental setup in which a travelling SAW, generated on the piezoelectric substrate by applying an AC electrical signal at the resonant frequency of the interdigitated transducer (IDT) electrodes, is transmitted into a film consisting of a cured polymer‐dispersed liquid crystal (PDLC) matrix that is placed atop the substrate. The right panel illustrates the effect of 34 dBm power of SAW on the liquid crystal morphology, a) initially, prior to the SAW excitation, and after b) 20 s, c) 40 s, d) 60 s, e) 80 s, and f) 100 s.
