Method for producing smooth surfaces on plastics

---

Abstract

---

Plastic objects are exposed to a gas mixture containing fluorine and a gaseous oxidizing agent, to produce an extremely smooth surface on the objects. The oxidizing agent can be oxygen, and the object is preferably exposed to the gaseous mixture for about 10-30 seconds. The surface of the object treated according to the present invention is found to be considerably more smooth and glossy than objects treated with fluorine alone, without the oxidizing agent. The surface formed according to the present invention therefore minimizes the contact area between the treated object and the surrounding media.
