The research aims to better understand the nanoscale interactions that drive mineral scale formation on polymer surfaces through combined experimental characterization and theoretical analysis. Specifically, the investigators will examine the effect of surface charge and hydrophobicity of polyamide films on mineral scaling rates. They will also employ liquid phase transmission electron microscopy to visualize and quantify mineral nucleation dynamics on polyamide surfaces in real time at the nanometer scale. Theoretical models will be derived for nanoparticle attachment and nucleation kinetics to identify the nanoscale interactions involved in scale formation as a function of polymer surface chemistry.

The results intend to facilitate rational manipulation of nanoscale mineral-membrane interactions to prevent unwanted mineral scaling on engineering polymers in aqueous environments. Educational outreach components include incorporating research findings into course materials and hosting joint student symposia on nanomaterials and water issues.
