(a) Schematic of a pure TiO2 nanoparticle film, where the surface-refunctionalized TiO2 nanoparticles are not cross-linked. (b) Schematic of a TE/TiO2 nanocomposite film, where the surface-refunctionalized TiO2 nanoparticles are covalently attached to the TE polymer network. (c) An eight-layer TE/TiO2 nanocomposite film containing 30 wt % TiO2. (d) An eight-layer TE/TiO2 nanocomposite film containing 90 wt % TiO2. (e) A two-layer TE/TiO2 nanocomposite film containing 40 wt % TiO2. (f) A two-layer TiO2 nanoparticle film containing 100 wt % TiO2. (c) and (d) are supported on glass substrates and used in the BLS measurements. (e) and (f) are supported on Si substrates and used in the 3ω measurements. The scale bars are (c) 1 μm, (d) 2 μm, (e) 500 nm, and (f) 100 nm.
