This article describes an approach to resolving the issue of evaporative loss from slippery liquid-infused porous surfaces (SLIPS). Hydrophobic and oleophobic fluids with significantly reduced evaporative loss rates at temperatures of up to 90 °C were obtained by the one-step mixing of commercially available perfluorinated lubricants with colloidal nanoparticles to form self-suspended nanoparticle fluids (i.e., suspensions nearly devoid of solvent). No evaporative loss was detected at temperatures of as high as 50 °C for over 3 months. Furthermore, the approach allows us to combine the function of the nanoparticles with the slippery characteristic of SLIPS.
