Web1 aug. 2015 · Surfaces with θ R <90° are shown to have definite affinities toward water and they are defined as hydrophilic. Surfaces that display lack of affinity with water are hydrophobic and their θ R is >90°. The underlying mechanism for hydrophobicity is discussed. Moreover, a surface is defined as superhydrophobic when its θ R is >90° and …
The hydrophilic–lipophilic balance (HLB) of a surfactant is a measure of its degree of hydrophilicity or lipophilicity, determined by calculating percentages of molecular weights for the hydrophilic and lipohilic portions of the surfactant molecule, as described by Griffin in 1949 and 1954.
