Evaluation of Temperature-Dependent Adhesive Performance via Combinatorial Probe Tack Measurements



A C. SMoon


We describe the design and application of a combinatorial probe tack apparatus for investigating the adhesive performance of model pressure sensitive adhesives (PSAs). In particular, we illustrate a methodology for studying the effect of temperature on critical adhesion measures such as adhesion energy and elongation at break of a model PSA comprised of poly(styrene-b-isoprene-b-styrene). To achieve this, a temperature gradient stage was constructed from a transparent sapphire plate with a heating and cooling source positioned at opposite ends. The substrate transparency is critical for simultaneous visualization of the contact area during the test, thus enabling the debonding mechanism to be studied as a function of the measurement temperature. When integrated with a motorized x-y stage, a matrix of probe-type tack tests can be conducted across the temperature gradient.Furthermore, an orthogonal gradient can be applied by introducing another parameter such as film thickness, contact time, velocity, or aging time. This experimental design provides significant reduction of experimental uncertainties associated with fabrication of multiple samples for a given set of experiments, as well as reduces the overall measurement time.
