Comments:
  • Deposition from aqueous alcohol solution is the most facile method for preparing silylated surfaces. A 95% ethanol-5% water solution is adjusted to pH 4.5-5.5 with acetic acid. Silane is added with stirring to yield a 2% final concentration. Five minutes should be allowed for hydrolysis and silanol formation. When both sides need to be processed, the sample is dipped into the solution. Cure of the silane layer is for 5-10 minutes at 110oC or 24 hours at room temperature.
