“…A combined system of a nanoindenter with dynamic force modulation AFM capability may be the best choice overall for combinatorial modulus measurements due to the robustness, accuracy, speed, and applicability (both bulk diffusion multiples and thin films). Other faster methods for modulus measurements [125,126] only have very niche applications.…”

“…[327] Force sensors record the forces applied oscillatorily by a pin array as a function of time, environmental conditions, and motion of the translation. This method allows the determination of the modulus and loss tangent of the samples as a function of time or temperature.…”

There is increasing acceptance of high-throughput technologies for the discovery, development, and optimization of materials and catalysts in industry. Over the years, the relative synchronous development of technologies for parallel synthesis and characterization has been accompanied by developments in associated software and information technologies. This Review aims to provide a comprehensive overview on the state of the art of the field by selected examples. Technologies developed to aid research on complex materials are covered as well as databases, design of experiment, data-mining technologies, modeling approaches, and evolutionary strategies for development. Different methods for parallel synthesis provide single sample libraries, gradient libraries for electronic or optical materials, similar to polymers and catalysts, and products produced through formulation strategies. Many examples illustrate the variety of isolated solutions and document the barely recognized variety of new methods for the synthesis and analysis of almost any material. The Review ends with a summary of success stories and statements on still-present problems and future tasks.

“…Kossuth et al [85] measured the complex modulus of elasticity and the loss tangent for 96 samples with the ''standard'' HTE format (8 Â 12 samples, spaced 9 mm apart) in parallel. Polystyrene-block-polybutadiene-block-polystyrene was deposited on a polyimide substrate, and on each spot a pin imposed a displacement oscillation while the force was measured.…”

Challenges and Progress in High‐Throughput Screening of Polymer Mechanical Properties by Indentation

Depth‐sensing or instrumented indentation is an experimental characterization approach well‐suited for high‐throughput investigation of mechanical properties of polymeric materials. This is due to both the precision of force and displacement, and to the small material volumes required for quantitative analysis. Recently, considerable progress in the throughput (number of distinct material samples analyzed per unit time) of indentation experiments has been achieved, particularly for studies of elastic properties. Future challenges include improving the agreement between various macroscopic properties (elastic modulus, creep compliance, loss tangent, onset of nonlinear elasticity, energy dissipation, etc.) and their counterpart properties obtained by indentation. Sample preparation constitutes a major factor for both the accuracy of the results and the speed and efficiency of experimental throughput. It is important to appreciate how this processing step may influence the mechanical properties, in particular the onset of nonlinear elastic or plastic deformation, and how the processing may affect the agreement between the indentation results and their macroscopic analogues.
