The free energy per molecule of a wedge in the strong segregation limit is the sum of stretching and interfacial contributions, $$f = f_{\mit int\/} + f_{\mit str\/}.
\label{eq:ftot}$$ The interfacial free energy per molecule is simply the surface tension contribution which, per chain, is $$f_{int}= {\gamma \,\Omega \, a(\beta)\, \over v(1)\, R}
\label{eq:interf}$$ where the surface tension $\gamma$ scales as $\chi^{1/2}$.[@helfand71] In the strong segregation limit we ignore the translational entropy of the junction points, which scales logarithmically with molecular weight and is thus subdominant.

The stretching energy is calculated by methods developed for polymer brushes,[@semenov85; @mwc88a]. The copolymer chains are added one by one, and the work to add each is summed. The
