Enhancement of the wetting of hydrophobic surfaces by aqueous surfactant solutions

摘要

A solid hydrophobic surface wetted with an aqueous solution that includes a first and second surfactant. The first surfactant includes a first straight-chain, branched chain or cyclic hydrocarbon chain and a first hydrophilic moiety. The second surfactant includes a second straight-chain, branched chain or cyclic hydrocarbon chain and a second hydrophilic moiety. The first and second straight-chain, branched chain or cyclic hydrocarbon chains may or may not be the same; the first and second hydrophilic moieties are not the same; and the first surfactant is added to the second surfactant in an amount that causes a synergistic increase in the spreading factor on the hydrophobic surface.
