Polyisobutylene (PIB) rubbers can be reinforced with crystalline β-alanine nanodomains. Progress has been made in understanding the morphology of the nanodomains, but the dynamics of the PIB molecule chains attached to the surface of the nanodomains and in the matrix are not well understood. It is possible to observe the motion of these PIB chains using Neutron Spin Echo (NSE) experiments, since the experimental technique can give data for smaller timescales. Data collection for reinforced rubber samples has already been performed, but the data still need to be analyzed. For my honors project I will be comparing the data to the predictions of theoretical models and doing nonlinear regression of the data with our candidate models. The project has useful applications in the biomedical industry due to the ability to control nanodomain size. The project will expand my understanding of polymer physics and will require the application of knowledge from applied math courses. The project will also improve my familiarity with scattering techniques, experimental data collection, and methods for analyzing scattering data.
