SUMMARY Microgels are colloidal dispersions of crosslinked polymer particles, which are most commonly prepared by emulsion polymerisation. Char acterisation in terms of particle size and surface properties is important in most practical applications.In more accurate way, milk is an emulsion (liquid in liquid colloidal system). In milk, butter and fat are dispersed in water. Bread is colloidal system in which air is dispersed in baked dough. Colloids also have applications in the form of medicines. Colloidal medicines are competitively more effective as they are easily absorbed by the body. application of colloidal dispersion
Dispersed phase and dispersion medium can be solid, liquid or gas. Depending upon the state of dispersed phase and dispersion medium
Colloids A colloid is one of the three primary types of mixtures, with the other two being a solution and suspension. A colloid is a solution that has particles ranging between 1 and 1000 nanometres in diameter yet are still able to Interactions in chargestabilized colloid Up: Configurational Temperatures and Interactions Previous: Derivation from the hypervirial Application to Colloidal Dispersionsapplication of colloidal dispersion Pharmaceutical applications of Interface and colloid science is a branch of chemistry dealing with colloid s, heterogeneous systems consisting of a mechanical mixture.
Dispersion of large particles or droplets to the colloidal dimensions by milling, spraying, or application of shear (e. g. , shaking, mixing, or high shear mixing). Condensation of small dissolved molecules into larger colloidal particles application of colloidal dispersion These particles range in size from 108 to 106 m in size and are termed colloidal particles or colloids. The mixture they form is called a colloidal dispersion. A colloidal dispersion consists of colloids in a dispersing medium. 16 Colloidal Dispersions Chapter Objectives At the conclusion of this chapter the student should be able to: 1. Differentiate between different types of colloidal systems and their main characteristics. 2. Understand the main optical properties of colloids and applications of these properties for the analysis of colloids. 3. Abstract: The interest in using colloidal dispersions of gelled lipid nanoparticles (GLN) for different elds of application has increased in recent years, notably in cosmetic, dermatology, andor pharmaceutics due to their capacity to immobilize compounds with poor water solubility.
