Abstract

There are few methods available for performing high-throughput adhesion measurements. Current high-throughput methodologies for measuring interfacial adhesion rely on serial or sequential testing of discrete or continuous libraries. Alternatively, we have developed a measurement platform that employs an array of lenses to simultaneously measure adhesion at multiple points on a substrate. We demonstrate the ability of this technique to characterize both the work of adhesion and adhesion hysteresis for a polydimethylsiloxane lens array against glass.In particular, we seek to quantify the effects of key system parameters on our ability to accurately measure adhesion with a multilens geometry in comparison to the traditional single lens geometry. We find the work of adhesion measured with the multi-lens array is within experimental error of single lens experiments. As a demonstration, we apply this multilens technique to a surface containing a gradient in surface energy created by controlled deposition of a n-octyldimethylchlorosilane monolayer, and we find the adhesion hysteresis to decrease with decreasing surface energy.
