STUDIES AND TESTING OF ANTIREFLECTIVE (AR) COATINGS FOR SODA-LIME GLASS

摘要

Experimental results on this feasibility study to establish processes for producing antireflection films on glass are very encouraging. Efforts have been concentrated in three areas: acid etching of glass, plasma etching of glass, and acid development of sodium silicate films on glass. The best transmission to date has been achieved through the acid etching technique, while the most durable films have been produced from development of sodium silicate films. Control of the acid etching technique is presently inadequate for production implementation, and large scale application methods for sodium silicate films need further definition. While films having excellent anti-reflective properties have been fabricated by plasma etching techniques, all have been water soluble, disqualifying the films from a weatherabiIity stand¬point.
