Abstract

The determination of Hansen Solubility Parameters (HSP) from inverse gas chromatographic (IGC) data for a group of nano-materials and modified nano-materials is presented and discussed.The solubility parameter concept is applied in many industries to explain the different properties of the various components in a formulation. Knowledge of the solubility parameter data for different components is important for predicting the magnitude of the interaction between the formulation components and the future stability of the product. Solubility parameter data are also useful in the description and interpretation of different phenomena occurring between materials such as their miscibility, compatibility or adsorption.The inverse gas chromatography method is widely used for the characterization of polymers and polymer blends, surfactants, biopolymers, solid food and petroleum pitches. The method involves placing the investigated material (stationary phase) in a column and then characterizing it using volatile prob...
