This chapter reviews the surface‐initiated ring‐opening metathesis polymerization (SI‐ROMP) of pNBFn films over the past 5 years. It describes the surface chemistry for growing pNBFn from different substrates, including smooth substrates, nanoporous membranes, and fibrous mats, as well as the kinetics for film growth as dependent on monomer concentration. The chapter examines the dispersive surface free energy of these partially fluorinated materials and further describes the ability to produce microtextured coatings through a combination of micromolding a master and surface‐initiated polymerization (SIP) of NBFn. A key advantage in the use of partially fluorinated polymer films is that the perfluoroalkyl components partition to the surface to reduce the surface energy. The ultralow surface energies for pNBFn coatings make them useful for many applications provided that the surface topography can be tuned to achieve distinct wetting states.
