Abstract

Considerable attention has been devoted to developing fabrication strategies for constructing combinatorial material libraries as well as tools for characterizing the chemical and physical properties of such libraries. Less attention has been dedicated to designing high-throughput metrologies for probing the engineering properties of combinatorial libraries. Here, we describe the design and refinement in our high-throughput buckling-based metrology developed to ascertain the mechanical properties (e.g., modulus) of combinatorial thin film libraries. To illustrate the combinatorial and high-throughput capability of this metrology, thin films possessing a gradient in modulus were generated by stacking two polymer films of disparate moduli possessing gradients in film thickness. The local thickness and modulus ratios of each component in the composite film then dictate the measured modulus of the laminate film as a function of spatial position.
