ABSTRACT:
A method for producing a transparent protective coating on a plastic optical substrate surface is disclosed. In particular, a substrate is positioned between two electrodes on the cathode in a reaction chamber. Once positioned, a noble gas is introduced into the chamber and the surface of the plastic optical substrate is bombarded. A monomeric organic compound of either siloxane or silazane is introduced into the reaction chamber and a bias voltage of a value in the range of 80 to 500 volts is obtained to polymerize the compound on the substrate surface. Following the beginning of this polymerization, oxygen is introduced into the reaction chamber in an amount of about 5 times the amount of the monomeric organic compound to form a mixture with the compound.
