Gradient and Microfluidic Library Approaches to Polymer Interfaces∗ Michael J. Fasolka, Christopher M. Stafford, and Kathryn L. Beers
Abstract We present an overview of research conducted at the National Institute of Standards and Technology aimed at developing and applying combinatorial and high-throughput measurement approaches to polymer surfaces, interfaces and thin films. Topics include (1) the generation of continuous gradient techniques for fabricating combinatorial libraries of film thickness, temperature, surface chemistry and polymer blend composition, (2) high-throughput measurement techniques for assessing the mechanical properties and adhesion of surfaces, interfaces and films, and (3) microfluidic approaches to synthesizing and analyzing libraries of interfaciallyactive polymer species.

1 Introduction: Surfaces and Interfaces in Polymer Science and Engineering The success of a huge range of polymer-based technologies, including advanced coatings and adhesives, electronics materials, complex fluid formulations and biomaterials, hinges on the ability to produce tailored polymer surfaces and interfaces. This is because surface and interfacial properties govern key aspects of product structure and performance, such as film and multilayer stability, mechanical reliability, adhesion, expression of functional moieties, component dispersion, and domain orientation, among others. Research dedicated to the understanding and engi
