Effect of the glass surface modification on the strength of methacrylate monolith attachment
چکیده انگلیسی
The influence of glass surface modification in order to determine strength of the monolith attachment was studied. Modification consists of pre-treatment of the glass with chemicals or boiling in deionized water, silanization and drying has been investigated on different types of glass. Amount of silane groups was determined by measurement of the contact angle between the glass surface and water drop. The highest values were found for soda-lime glass. Strength of the monolith attachment was established by pumping ethanol through the monolithic capillaries and measuring the pressure drop at which monolith was dislodged. Surprisingly, it was found that the critical part of the glass surface modification procedure is glass pre-treatment. Good results were obtained with glass boiled in water for 2.5 h or more.
