Model Polymer Thin Films to Measure Structure & Dynamics of Confined, Swollen Networks
Sara V. Orski, Edwin P. Chan, Kirt A. Page, Kathryn L. Beers
In this chapter, we discuss applying X-ray reflectivity to study the structure and dynamics of dense and ultrathin polymer films upon exposure to solvent vapors. These vapor swelling studies permit the measurement of thermodynamic parameters using established mean-field models such as Flory-Huggins, Flory-Rehner, and Painter-Shenoy to understand the elastic contributions to swelling, as well as the polymer solvent interaction parameter of these confined films. This chapter describes the various experimental approaches to leverage mean-field theories towards describing and understanding swelling behavior of thin film networks and brushes, the applications, and their limitations.
