永久性大孔（>50 nm）在液态下尚未被报道，直到最近Tao Li及其同事描述了一种合成策略以形成具有双重微孔-大孔性的多孔液体。 这是通过生产表面涂覆并通过分散流化的分级多孔颗粒来制备的。表面微孔通过流体相的空间排阻实现永久多孔性。由于大的（480 nm）未被占据的大孔，该材料具有相当大的吸水能力（27% w/w）。 这也使得能够在吸收水时切换热导率。这些是从多孔固体转化为液态的新特性。
Permanent macropores (>50 nm) had not been reported in the liquid state until a recent report by Tao Li and co‐workers describing a synthetic strategy to form a porous liquid with dual micro‐macroporosity. This is prepared by producing hierarchically porous particles that are surface coated and fluidised by dispersion. Surface micropores enable permanent porosity by steric exclusion of the fluid phase. The material has a considerable water uptake capacity (27 % w/w) due to large (480 nm) unoccupied macropores. This also enables switching of thermal conductivity on uptake of water. These are new properties translated from porous solids to the liquid state.
