A simple weighted density functional approach is employed here for predicting the structure of polymers at interfaces where the polymer molecules are modeled as freely rotating fused-hard-sphere chains with fixed bond lengths and bond angles. The approach treats the ideal gas free energy functional exactly while the excess free energy functional is… CONTINUE READING
