The study on Surface organic modification of silicate glass

The hydrophilic acrylic acid was used to modify the glass by grafting acrylic acid onto the plasma treated glass surface under the catalyzer of H2SO4. The results were analyzed from two aspects of composition and structure by attenuated total reflection FTIR (ATR-FT-IR) and tensiometer, respectively. Research shows that acrylic acid was grafted onto the glass successfully; moreover, the competition between grafting reaction of carboxyl and hydroxyl groups and self polymerization of acrylic acid had close relationship with the concentrations of sulfuric acid, when the concentrations of sulfuric acid was14%, the hydrophobic effect was the best.
