Hansen solubility theory

WebNov 15, 2024 · The distance between the solvent and solute in the Hansen solubility sphere is calculated as follows [8]: (3) R a = 4 ( δ ds - δ dl) 2 + ( δ ps - δ pl) 2 + ( δ hs - δ hl) 2 where the subscripts s and l denote the solvent and polymer, respectively. If R a is inside the sphere, that is, R a < R 0, then the solvent can dissolve the polymer. Hansen solubility parameters were developed by Charles M. Hansen in his Ph.D thesis in 1967 as a way of predicting if one material will dissolve in another and form a solution. They are based on the idea that like dissolves like where one molecule is defined as being 'like' another if it bonds to itself in a similar way.
