Controlling material degradability through stereochemistry

Many plastics are used by humans for only a few minutes before being discarded to sit in a landfill for generations. New strategies to degrade plastics are urgently needed, and fundamental stereochemistry may provide a solution. Recent reports have shown synthetic polymers that adopt elongated linear conformations, rather than globular spherical ones, are more rapidly degraded by shearing forces into their constituent monomers. Typically, modifying this morphology requires changing the monomer identity and manipulating either sterics or charge. Instead, we will leverage stereochemical control of polymer backbones to dictate the overall chain conformation. This project will therefore involve both synthesizing polymers with variable backbone stereochemistry, and investigating their morphology and degradation profiles.  

Essay prompt: In 1-2 paragraphs, please describe what motivates you to pursue this research opportunity, and what you are hoping to learn. Please also include at least one question you have about the proposed research.

Name of research group, project, or lab
Brucks Research Group
Why join this research group or lab?

The Brucks research group is a new team at Harvey Mudd, and all students joining will have the opportunity to help establish our foundation. This specific project will afford training in techniques from both organic chemistry and polymer science, including characterization with NMR, size-exclusion chromatography (SEC), and ultrasonication. In addition to lab techniques, supportive collaboration and effective communication of results will be heavily emphasized. Our growing team will always center respect and inclusivity to foster an environment where everyone can succeed.

Student qualifications

We welcome all who are interested in experimental interdisciplinary science, especially those with identities that have been historically excluded from STEM. Preference will be given to individuals who may be interested in continuing this research during summer 2023, and who have completed at least one semester of organic chemistry lab (Chem 58 and Chem 111).
