Figure 4 caption: Photoresponse of a rectangular LCE strip (90 μm thick) with uniaxial orientation of the director along the long axis of the element with (a−c) low UV intensity (365 nm, 50 mW/cm2) and (d−f) high UV intensity (365 nm, 200 mW/cm2) exposure. A weight of 1 g is attached to the lower extreme of the strip. (a,d) Images of the LCE element successively acquired (i) before UV illumination, (ii) after UV illumination (after 4 and 1 min of illumination with 50 and 200 mW/cm2, respectively), (iii) 2 min after ceasing the UV illumination, and (iv) after 30 min of blue light illumination (455 nm, 4 mW/cm2). (b,e) Temporal dependence of normalized strip length during the initial part of the experiment showing contraction upon UV illumination (purple squares) with (b) 50 and (e) 200 mW/cm2 and the partial recovery of the length when UV illumination ceases (black squares). (b and d insets) Temporal dependence of normalized strip length during the whole experiment including the final blue light irradiation step (455 nm, 4 mW/cm2, for 30 min, blue squares). (c,f) Temporal dependence of temperature of the irradiated side of the LCE element illuminated (365 nm, purple line) with (c) 50 and (f) 200 mW/cm2.
