Abstract
A method for reducing the tendency of a surface of a material to foul when exposed to a potential foulant comprises the step of treating the surface of the material with a plasma of a compound containing or generating hydroxyl groups to render the surface hydrophylic but substantially uncharged. The materials may be inorganic, e.g. glass, or organic, e.g. polyamide, and may be in the form of fibers, woven fabrics, membranes or plates. Suitable compounds containing hydroxyl groups include ethylene glycol and water.
