Low adherence coating containing polymers with low surface energy

A low adherence coating comprises: (a) a crosslinked polymeric network (N), based on a first polymer (P), (b) a low-surface-energy group (E), coupled to the network via (c) a polymeric spacer (S), having the following relationship between the native surface energies of P, E, and S (resp. sp, se, and ss,, in mN/m): se <ss <sp. The coatings have a low adherence towards different types of contaminants. A coating contained a polycaprolactone terminated with perfluorooctyl ethanol. [on SciFinder (R)]
