Fig. 6. SAXs data of PS-OS@SiNR liquid samples prepared from SiNRs with aspect ratios of 2.5 (1.3), 8 (6.6), and 11 (7.3). The data were collected at 25 °C and subsequently corrected for the background. The data set for PS-OS@SiNR-2.5, 8 and 11 has been vertically shifted by a factor of 2, 1, and 60, respectively, for the ease of viewing. The inset shows the apparent structure factor (Sapp(q)) of the porous liquid samples obtained by using bare and hollow SiNRs as the form factor. Sapp(q) shows correlation peaks at q values of ∼0.015, 0.016, and 0.018 Å−1 for the PS-OS@SiNR-2.5, 8, and 11 samples, respectively, corresponding to d spacing values of 40, 38.5, and 35 nm which occur due to the side-to-side assembly of hollow silica nanorods (inset) in the solvent-free PS-OS@SiNR composite sample.
