FAST AND ECONOMICAL GLASS FUNCTIONALIZATION IN ONE STEP

The present invention provides a method of one step ion exchange for functionalization thin glasses by strengthening and controlling the optical properties. Owing to controllable optical transmittance and absorbance properties, these thin glasses can be utilized as solar control glasses. A paste containing potassium compound and silver compound was applied to the glass substrate containing an alkali metal component by screen printing, thereafter ion exchange heat treatment was performed below glass transition temperature. The method of the invention can produce a glass with surface compressive stress between 550 and 600 MPa, compressive stress layer in the range of 10-15 µm. In the antimicrobial activity test, the amount of alive E.coli bacteria decreased ≥99.9% after 24 hours of contact time. Thin glasses, in which the optical transmittance values are controlled depending on the ion exchange process conditions, spectrally selective, chemically strengthened and showing antimicrobial surface properties that are in accordance with the requirements of the application area, were produced by one step ion exchange.
