UVO Wand for Surface Energy Gradient

Any UV-ozone (UVO) sensitive substrate/polymer coating/self assembled monolayer"s can be cured or oxidized in gradient manner or uniformly using the aluminum encased UV wand with 1 mm slit opening in conjunction with an accelerating stage. The UVO exposure time and distance from substrate dictate the final surface energy/dose of the substrate. Substrates with surface energy gradients from 20-76 mJ/m2 can be produced with this instrument.
