This set contains the data underlying Figures 1, 2, and 3 in the publication "Unfavorable Interactions Enhance Vapor Absorption in Mixed Polymer Brushes". Figure 1: Heat map of solvent density profile in a pure, striped and mixed brush. Figure 2: Enhanced absorption in striped and mixed brushes compared to pure brushes for varying polymer incompatibility. Figure 3: Absorption isotherms for pure, striped, and mixed polymer brushes and the enhanced absorption of striped and mixed brushes compared to pure brushes.
