Nanocomposite films and interfaces are ubiquitous in everyday life. Common cosmetics, paints, coatings, and varnishes as well as electronic devices utilize nanomaterial components in specific layers. Experimental characterization of these materials is critical to material improvements, within, for example, functionalized paints to deter bacteria growth in sterile settings, and future device developments, including smart contact lenses and smart windshields for self-driving cars. This dissertation characterizes two different nanocomposite film systems using novel application-driven experimental techniques.In the first instance, I use surface-sensitive infrared reflection absorption spectroscopy to probe interfacial interactions and adhesion in graphene-polymer laminar composites. I connect molecular movement as induced by graphene to overall film adhesion using a spatially resolved optical transmission technique that quantifies graphene coverage as a function of film area. We find that polymer chain composition and conformation strongly affect interfacial adhesion, and laminate interactions can be fine-tuned to enhance film stack adhesion. The optical transmission data are collected on an in-house laser system. Data analysis are expanded to provide automated, statistically relevant information about the graphene spatial distribution as well.In the second instance, we modify an x-ray scattering technique to quantify local particle concentrations in self-assembled nanofilms. This methodology probes beyond the sample surface and can be applied to in situ studies. Through a novel fitting process, we observe three different stratification regimes as induced by the small particle size. We apply this technique to another system and present two new film configurations that have not been characterized or theorized previously. I computationally model these data using leading theory to probe the limits of diffusion-based theoretical approaches and demonstrate complex stratification in different realistic systems. From these experiments, we find that both the initial particle concentration and the particle size ratio strongly impact the final self-assembled film structure.
