47. The formation of negative and positive radii of curvature in the presence of salt in relation to the actions of crowns is difficult to reconcile. However, it is well documented in the literature that added cations increase the screening between the AOT headgroups and hence allow the headgroups to be closer in the aggregate. Such a modification of the aggregate structure implies an increase in the natural tendency of the surfactant for negative curvatures and increases the percolation temperature. When cations are complexed by crown ethers, they can penetrate deeply in the interface so that the screening effect should be larger than that in the absence of crown ethers
