Fig. 3. Schematic showing the three-step procedure for the fabrication of the anisotropic porous liquid from SiNRs involving covalent coupling of an organosilane (OS) canopy on the surface of bare and hollow SiNRs, electrostatic coupling of anionic polymer surfactant (PS) chains to the OS@SiNR followed by extraction with toluene to remove excess PS, and heating to 70 °C for 1 h at low pressure to remove toluene yielding the PS-OS@SiNR based anisotropic porous liquid.
