Abstract:
A method of photochemically modifying a solid surface of a fluoroplastic material, comprising;providing a liquid containing a chemical species selected from (a) a liquid compound and (b) a solution of a compound in a solvent;containing said liquid with said surface and a window member to form a layer of said liquid, said window member being substantially transparent to ultraviolet, visible or infrared radiation and positioned in relation to the fluoroplastic material such that capillary force is exerted upon the layer of said liquid to form and maintain an interface between the liquid and said surface, andapplying said radiation through the window member onto the interface to effect a reaction of the chemical species with, and thus modify the surface of, the fluoroplastic material by liberating fluorine.
