Project Title: Adsorption behavior for small molecules of polymers grafting from nanoplatelets

Collaborators: Daeyeon Lee (CBE)

Funding Source: Japan Science and Technology Agency

Project Description: In this work, the adsorption of small molecules such as hexane, methanol, and CO2, for poly(methyl methacrylate) (PMMA) grafting from plate-shaped nanoparticles is studied using a QCM instrument equipped with a vapor pump system.


Postdoctoral Researchers


Dr. Shreyas Pathreeker
Postdoctoral Researcher
(MSE)

spathree@seas.upenn.edu

Education: Ph.D., Chemical Engineering, Syracuse University, NY

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: 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.

Education: B.S. in Materials Science and Engineering, University of Maryland College Park

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.
