The Influence of Different Surface Compressive Stress on the Wettability of Ion-Exchanged Float Aluminosilicate Glass

The effect of the surface compressive stress (CS) on the wettability of the chemically strengthened glasses on air side and tin side was investigated. The wettability of the air side of the raw glass is better than the tin side. After chemical strengthening, the surface energy of the air side decrease with the decreasing of the CS while the tin side is just the opposite. These results demonstrated that the wettability of the chemically strengthened aluminosilicate glass could be controlled by the compressive stress.
