dc.description.abstractA phenomenon was observed during work producing "ultra-thin glass" (<150μ thickness) where samples folded onto themselves displayed strong adhesion and served as a simple method to analyze contaminants in the process and packaging of resulting ware. Subsequent Contact Angle, Wedge Test, and T-Peel studies were performed to understand the baseline of Surface Free Energy (SFE) for this direct bonding and attempts were made to refresh aged and packaged samples through various cleaning steps to produce a similar effect. When results showed SFE change was minimal between aged, cleaned, and fresh glass and no treatments enabled similar direct bonding to fresh samples, 90° and 180° Peel Test with adhesive tapes and films were used as a surrogate to rank the effectiveness of attempted cleaning procedures. Such tests yielded widely ranging values inherent to known issues with peel testing, but provided useful data to calculate true adhesion values of just 2 - 2.5 N/m, which were 1 to 3 orders of magnitude less than the experimental values due to work absorbed by elastic/plastic effects when peeling the polymer adherend. Highly flexible glass samples do not experience plastic deformation, so studying direct bonded ultra-thin glass provides a unique perspective on adhesion studies by excluding plastic effects. It was also demonstrated that although the direct bonded samples had even lower peel strengths after initial separation, the bond strength was higher than strong tapes and even epoxy prior to edge-crack formation, showing the usefulness of direct bonding in optical materials and potential for future development.en_US
