To provide materials that resist fouling and methods for identifying the same.SOLUTION: In general, the present invention is directed to materials that when in use resist fouling on their surfaces. Such materials may be used in a construction of various process devices having surfaces exposed to given fluid that contains a foulant or chemical substance, which may deposit on or adhere to the surface and thereafter continue to grow on the surface resulting in deteriorated performance of the devices and processes. The materials are specifically selected using a method that takes into account dielectric spectra of the fluid to which the surface is exposed and the surface itself. It has been unexpectedly found that if the dielectric spectra of the surface and the fluid are matched in a range of relative agreement, there should be no adhesion of the foulant substance on the surface. In some embodiments, the dielectric spectra to be matched include intrinsic indexes of refraction.SELECTED DRAWING: Figure 1
