Surface modification using light is one of the most powerful methods for controlling the physical and chemical properties of functionalized surfaces. In this paper, we report on systems where soft UV irradiation (λ = 365 nm) converts a “low” activity fluorocarbon to a “high” activity amine-functiona...
