Introduction of colloidal systems and their classification, origin of charge on colloidal particles, stabilization of different colloidal system by surfactants, solubilisation, emulsions, microemulsions, HLB, micelle formation by surfactants, thermodynamic parameters of micellization, emulsification by surfactants, micellar catalysis, synergism in mixture of two surfactants.
Fundamental aspects of colloidal suspensions, surface tension, wetting, surfactant adsorption, self-assembly, and inter particle interactions, as well as the importance of these phenomena to consumer, industrial, and biomedical applications.
Intermolecular, nanoscale and interfacial forces in organic, polymeric, biological and aqueous systems. Van der waals, electrostatic double layer, acid-base interactions including hydrophobic attraction and hydration pressure.
Mesoscale thermodynamics and Mesoscale phenomena in soft matter & applications Gibb’s treatment of interfaces, concept of excess concentration, variation of interfacial tension with surface concentration, Adhesion, wetting, nucleation, flotation, patterning of soft material by self organization and other techniques.
Stability of thin (< 100 nm) film, self-organization in confined systems, mesoscale patterning. Super hydrophobicity, functions coatings, structural colours, nano-adhesives, nanocomposites.
