Implications of Diversity: A Study of the Evolution of the Adsorption States of Macromolecules at Surfaces

We study the adsorption of macromolecules from solution onto single solid surfaces, focusing on the evolution of compositional heterogeneity of the layer. The origin and development of adsorption states within the physisorbed layer is noted in both chemically homogeneous and heterogeneous layers and is inferred from measurements of surface excess, bound fraction, segmental orientation, and adsorption-desorption kinetics made using Fourier transform infrared spectroscopy in the mode of attenuated total reflectance. The macromolecular systems studied were intentionally varied with regard to chemical composition, surface affinity, flexibility, and solvent quality and concentration.
