Fig. 2. Effective interface potential (left) and corresponding disjoining pressure (right) vs film thickness as predicted by DLVO theory for an aqueous soap film containing 1 m M of 1:1 electrolyte. The local minimum in V(‘), marked by �, gives the equilibrium film thickness in the absence of applied pressure as 130 nm; the disjoining pressure P ¼ �dV=dl vanishes at this minimum. The minimum is extremely shallow compared with the stabilizing energy barrier. To convert kPa to atm, divide by 102. mN=m ¼ dyn=cm ¼ ergs=cm2.
