Abstract
Surface properties of solids are of high interest due to their importance in microelectronics, sensors, bio-materials, and adhesion. Surface energy is particularly important in chemical sensors and biosensors since it affects the sorption of molecules onto the active area of the sensor and the adhesion of sensing films. Surface energy has traditionally been quantified by contact angle measurements, however, the contact angle technique has several drawbacks including hysteresis, poor reproducibility, and the inability to measure small angles. The objectives of this research were to study the effects of several treatments on glass and quartz using contact angles, scanning probe microscopy, surface roughness, and a novel dewpoint error technique, in order to develop a better understanding of the effects of surface treatments. The dewpoint error technique was also examined as a novel method for measuring surface energy that may have advantages over contact angle measurements. The treatments studied in this work included acids, bases, etchants, polishing compounds, sputtering, adhesion promoters, anp metal surfaces.
