a) Absorption spectrums of Sample SP3 at different elongations. b) Photograph of Sample NP2 at 0% and 100% elongation. c) FTIR spectra of ATO nanoparticles before and after modification by KH590. d) TEM images of (i) the virgin ATO NPs and (ii) the modified ATO NPs whose dispersibility is obviously improved. e) Photos of the virgin and the modified ATO NPs dispersing in the organic solvent (tetrahydrofuran). f) SEM‐EDS mapping diagram of Sample NP2, the elements of Sb and Sn are evenly distributed in the matrix. g) Absorption spectra of Sample NP2 at different elongations. h) Photograph of Sample NP2 at 0% and 100% elongation.
