Solvent hating colloidal system
WebLyophilic Colloids O Systems containing colloidal particles that interact to an appreciable extent with the dispersion medium. O Also known as solvent-loving colloids. O Owing to their affinity for the dispersion medium, such materials form colloidal dispersions, or sols, (Sol is the colloidal dispersion of a solid in liquid or WebIn this kind of colloid, the forces between the colloidal particles are not stable and strong, and it is also known as lyophobic colloids. The word, lyophobic comes from two terms, lyo which means liquid, and phobic which means fear. Hence, they are also considered solvent-hating colloids as they create repulsion force against the water molecules.
