				   surface tension decreases during formation of lyophilic colloids

6 years ago


Answers : (1)


Dear naveen,

In lyophilic colloids, the particles in the dispersed phase undergo intensive interaction with the molecules of the the surrounding liquid. The particle surfaces are strongly solvated, and the specific free surface energy (surface tension) at the separation boundary is extremely low. The conditions necessary for the formation of lyophilic colloids are achieved at room temperature if the interphase (surface) tension does not exceed several hundredths min.m–1 (–1).

Lyophilic colloids are formed by the spontaneous dispersion of large clumps of a solid or drops of a liquid into minute colloidal particles (micelles). Such colloids are thermodynamically stable and therefore do not disintegrate when kept under the conditions necessary for colloid formation. The lyophilic colloids include critical emulsions (that is, emulsions formed near the critical displacement temperature for two interacting liquids), the colloidal dispersions of micellar surfactants (soaps, certain organic pigments, and dyes), and the aqueous dispersions of bentonite clay.
