Abstract :Polymeric micelles supply an environment, which can be cautiously regulated for drug delivery. The self-assembly of polymeric micellization is dynamic. Micellization thermodynamic describes how the system defines the formation of micelles. The present study enables the micellization behavior of the surfactants in the presence of polymer to be examined by conductometric and tensiometric methods. The effects of polymer concentration and temperature on the micellization thermodynamics of a neutral soluble polymer and cationic cetyltrimethylammomium bromide insert ignore into journalissuearticles values(CTAB); surfactant mixture in aqueous medium were investigated. To examine polymer-surfactant interaction, critical micellar concentration insert ignore into journalissuearticles values(CMC); and thermodynamic parameters such as standard free energy ∆G, enthalpy ∆H and entropy ∆S are calculated by using a pseudo-phase model. Based on CMC, ΔG, ΔH and ΔH, the dependence of the compensation temperature on the polymer effect is discussed. This advanced work to understand micelle stability and compatibility can be comprehensively feasible in polymeric systems.
