a UV-vis transmittance spectra and photos (inset) of polymer films with a phenyl substituent (Ph film, left) and an N-ethyl carbazolyl substituent (Cz film, right), respectively; thickness of the films: 0.20 mm; scale bar = 2.5 mm. b Schematic illustration of the process of the wear resistance test (UV light: wavelength = 365 ± 3 nm, power density = 40–42 mW cm−2) of the Ph film (top) with corresponding photos and UV-blocking rates of each stage (bottom). c Comparison of the Cz film with recently reported HEBL-shielding films in terms of the HEBL-blocking ability (blocking rate at 450 nm) and visible light transparency (transmittance at 650 nm). Different shadings represent that the data come from different references.
