Project Title: Solid Polymer Electrolytes for Sodium-ion Batteries
Collaborator: Prof. Eric Detsi (MSE)
Funding Sources: NSF-FMRG
Project Description: My research is focused on the development and characterization of solid polymer electrolytes for sodium-ion batteries. My main project is centered around developing 3D batteries, and I also carry out fundamental research on structure-property relationships in planar composite polymer electrolytes to improve both ionic conductivity and ion selectivity. Key areas include polymer coating strategies, polymer crystallization in composite media, dielectric spectroscopy, and ion-filler interactions.

Project Title: Structure Dependence of Polymer Nanocomposites
Collaborator: N/A
Funding Sources: NSF-DMR, NSF-PIRE, NSF-NRT, NSF-GRFP, NSF-MRSEC
Project Description: The properties of polymer nanocomposites (PNC) depend on a large parameter space, including processing conditions like temperature and film thickness. My project aims to elucidate the impact of these parameters, specifically film thickness and nanoparticle loading, on the PNC structures, and by extension, their resultant properties.

Project Title: Polymer Infiltrated in Bicontinuous Nanoporous Scaffolds: Polymer Kinetics and Nanocomposite Properties
Collaborators: Zahra Fakhraai (Chemistry), Eric Detsi (MSE), Eric Stach (MSE)
Funding Sources: VIEST, NSF/DMR, ACS/PRF
Project Description: Polymer composites have been widely studied because of their outstanding properties. Typically, polymer nanocomposites (PNC) are fabricated by adding inorganic nanofillers to a polymer matrix. In my project, a high-filler PNC is created by infiltrating and/or grafting polymers into a nanoporous gold scaffold exhibiting a bicontinuous structure and nanoscale pores. The goal for this project is to investigate the polymer kinetics behavior inside confined nanoporous gold media and characterize the optical properties of the formed nanocomposites.

Project Title: Probing Nanoparticle Dynamics and Kinetics of Adsorption to Polyelectrolyte Brushes
Collaborators: Co-advised: Karen I. Winey (MSE & CBE)
Funding Sources: NSF CBET
Project Description: Currently, nanoscale separation technologies are limited in their scope of adsorption in situ and in real-time. My research focuses on the interactions of gold nanoparticles (AuNPs) to the weak polyelectrolyte brushes, poly(2-vinyl pyridine) (P2VP), which are stimuli-responsive to pH changes. The structural changes influenced by pH are leveraged in my research to elucidate the mechanism of pH-mediated size-selective adsorption to homopolymer P2VP brushes in relation to brush molecular weight, grafting density, and grafting surface.

Project Title: Autonomous Exploration of Process-Structure-Property Relationships in Polyelectrolyte-Based Polymer Nanocomposites
Collaborators: N/A
Funding Sources: NSF DMRand NSF NRT
Project description: My research is on the development of autonomous experimentation methods to study process-structure-property relationships in polyelectrolyte-based polymer nanocomposites (PE-PNCs). PE-PNCs have the potential to serve as solid polymer electrolytes (SPEs) for batteries, but much less research has been done on this topic compared to the process-structure-property relations for neutral PNC materials. This research hopes to bridge that gap in literature through employing autonomous experimentation methods to more efficiently and more sustainably navigate through experimental campaigns to design favorable PE-PNC materials.
