It turns out that the surface science community has provided surprisingly few tools relevant to those needing to produce functional coatings. An over-emphasis on ‘surface energy’ and DLVO, both of which involve much handwaving and surprisingly little good science, has meant that we have missed out on many tools that are much more insightful. In this talk, a number of such tools will be shown, live, via the apps that implement them, including the super-sophisticated Scheutjens-Fleer theory for dispersants/stabilizers which has been appified recently. All apps are free and Open Source. This appification of knowledge is a key way to allow busy formulators to test their formulation options. For those who need more depth than the explanations on the app pages, they can download free eBooks that go into more detail, yet link directly to the apps so you can see what the science means for your problems.
