In general, the present invention is directed to materials that when in use resist fouling on their surfaces. Such materials may be used in the construction of various process equipment having surfaces exposed to a given fluid that contains a foulant or chemical substance that may deposit on, or adhere to, the surface and thereafter continue to grow on the surface resulting in deteriorated performance of the equipment and process. The materials are specifically selected using a method that takes into account the 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 to within relative agreement, there should be no adhesion of the foulant on the surface. In some embodiments, the dielectric spectra to be matched include the intrinsic indexes of refraction.
