• favourable electrostatic interaction between the sheets of the three. The fact that the Class 6 polymorph is comprised of antiparallel β-sheets stacked in a parallel configuration places it intermediate between the other two. The correlation between the peak force and the electrostatic interfacial energy

• deformation. (3) If the fibrils contain a high degree of order at the interface being interrogated, and if the pulling mode applied results in a substantial separation of this interface, then the peak force required to cause mechanical failure of the fibril will be correlated with the interfacial energy. This

• preparation of heterogeneous surfaces. The proximity of macroscopic phase boundaries affects the orientation of the nanodomains as well as the film structure. Parameters, which govern the orientation, are the interfacial energy of the boundaries [121][122] and the film thickness [123]. In the case of lamellae

• micelle with outer radius and thickness a. The free energy of the micelle can be written as a sum of four contributions: The first term, Fint, is the interfacial energy: Here, and . The first term in Equation 3 is the energy of interactions of the A side chains with the substrate and the air; and are

• shell of the micelle can be written as: Here, the volume per monomer unit is assumed to be equal to the cube of the segment length. The last condition corresponds to the fact that the backbone of each particular brush molecule is almost fully stretched. Using the above conditions, the interfacial energy

• superhydrophobic surface [18][19]. Results and Discussion 1. Droplet wrapping theory To assess whether it is energetically favourable for a liquid to become wrapped in a solid we consider the change in interfacial energy as the solid–vapor interface is replaced by a solid–liquid interface together with the
