WebApr 5, 2024 · Coagulation of Lyophilic sols. Lyophilic sols are more stable than lyophobic sols. The stability of lyophilic sols is due to two factors : 1) Charged and. 2) Solvation of the colloidal particles. When these two factors are removed, a lyophilic sol can be coagulated. This can be done (i) by adding electrolyte and (i) by adding suitable solvent. WebThe formation process of silica nanoparticles by the addition of tetraethylorthosilicate (TEOS) to an buffered, aqueous solution of lysine, is discussed. Optically clear mixtures can be prepared from lysine, TEOS, and water to give a specific molar composition.
