Hierarchical Network-Augmented Hydroglasses for Broadband Light Management

Figure 1

The hierarchical structures of the hydroglass. (a) The photograph of the monomer aqueous solution (MAA doped with about 550 mM positive charge concentration of the trivalent aluminium cation). (b) Optical micrographs of the monomer aqueous solution during the LCP process. Scale bar: 100 μm. (c) The time-dependent FTIR results of the monomer aqueous solution during the LCP process. D2O was used as the solvent to eliminate the influence of δ(O-H) band of water at about 1640 cm-1. (d) The photograph of the HNAH. (e) The cryosection micrographs of the HNAH with different slice thickness for the observation of micronetworks and nanonetworks (from left to right) and their schematic models. Bule and red dash lines indicate the micro- and nanonetworks in the HNAH, respectively. The scale bars are 0.5 μm and 200 nm, respectively. (f) Schematic models of the hierarchical networks of the HNAH.
