Abstract
Materials and methods for modifying surfaces in order to change surface energy are provided. These surface properties cause the surface to become more hydrophobic or oleophobic after light exposure. The ability to change surface energy upon exposure allows these materials to be patterned and enables a variety of uses, notably for use on semiconductor substrates in photolithography.
