Abstract:
1. A surfactant-free aqueous suspension, comprising water, hydrophobic nanostructured particles and an organic solvent; wherein the surfactant-free aqueous suspension is prepared by a process comprising: wherein the surfactant-free aqueous suspension comprises at least 50.01% by weight of water; wherein the hydrophobic nanostructured particle has an average diameter of from 30 to 100 μm and is present in an amount of from 0.01 to 1% by weight based on the total weight of the surfactant-free aqueous suspension; and wherein the hydrophobic nanostructured particles are particles of polytetrafluoroethylene; and wherein the hydrophobic, nanostructured particles are not agglomerated.
