What is the structural component of disjoining pressure?

  1. Dec 12, 2014 #1
    It is widely believed that there are three components of disjoining pressure: the dispersion component (Van der Waals), the electrostatic component and the structural component. For the first two, there are some accepted formulations for calculation. However, I cannot find any equations for the structural components. Is there any papers that give an explicit equation?

    Structural effects on physical properties aren't regular enough to be summed up in any sort of cookbook equation, sorry. If you read carefully, you'll find the other two components have a "molecular area" approximation built into them.
