Abstract

The contact angles of aqueous solution of Triton X-100 and Triton X-305 for airwater-quartz and cyclohexane-water quartz systems have been studied. It has been found that the equilibrium contact angle (measured through water) against quartz is increased by the addition of small amounts of nonionic surfactants, but beyond a certain concentration the angle decreases again. Based on the bilayer adsorption model on quartz/water interface, the experimental results can be explained.

Key words
