Group contribution method for the estimation of contact angle trends on modified polymer surfaces.
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.
