Contact angle measurements can determine the surface energy, γ, of a solid. To accurately measure the surface energy, we must use a set of fluids and the Lewis acid/base theory with the contact angles, θ, for each fluid. However, a simple contact angle measurement with water will give an approximate answer. This is useful because almost all "contaminants" on a surface affect the measured surface energy.
