Fig. 3: Working mechanism and UV shielding ability.

From: Azobenzene-containing liquid crystalline composites for robust ultraviolet detectors based on conversion of illuminance-mechanical stress-electric signals

Fig. 3

OM images of the ILCP fiber networks a before and b after UV irradiation. c UV induced contraction stress curves in accordance with UV power density. d Schematic diagram of the conformal and recyclable UV shielding LCP fabrics. e Transmittance spectra of the LCP-TPU fabrics, commercial products (CPs), and nitrile gloves (NGs), respectively. f The normalized UPF of original samples, 100% strain stretched samples and water washed samples, respectively. The normalized UPF is defined as the ratio of UPF over the film thickness. g Photographs of the UV shielding property evaluation upon 20 mW cm−2 UV light by photochromic spiropyran indicator (10−5 mol/L, ethanol solution). The four samples are (1) blank group, (2) LCP shielding group, (3) nitrile shielding group, and (4) no shielding group, respectively.
