Abstract
A plasma is produced in a treatment space (58) by diffusing a plasma gas at atmospheric pressure and subjecting it to an electric field created by two metallic electrodes (54,56) separated by a dielectric material (64), a precursor material is introduced into the treatment space to coat a substrate film or web (14) by vapor deposition or atomized spraying at atmospheric pressure. The deposited precursor is cured by electron-beam, infrared-light, visible-light, or ultraviolet-light radiation, as most appropriate for the particular material being deposited. Additional plasma post-treatment may be used to enhance the properties of the resulting coated products.
