title: Group contribution method for the estimation of contact angle trends on modified polymer surfaces.
abstract: Group contribution methods can be used as an aid in evaluating contact angle data on modified polymer surfaces. Good correlation was seen between experimental contact angle titration data on a hydrolyzed polyimide surface and equations involving water-octanol partition coefficients using parameters derived from group contribution methods. The methods used captured features of the experimental contact angle titration data observed during ionization of surface functional groups.
