Microplasmas were used for the surface treatment of small-diameter polyethylene (PE) tubing. The density of the microplasma was measured using a microwave cavity disgnostic. A monochromator helped in observing plasma light output at various positions along the PE tube to assess uniformity. To the lumenal surface of the PE tubing, a poly(ethylene oxide) surfactant was immobilized with an argon microplasma discharge. The properties of the inner surface of the PE tubing and the emitted light intensity indicated a correlation.
