Polyzwitterion fast and slow mode behavior are coupled to phase separation as observed by dynamic laser light scattering

September 11, 2023

Author(s)

Phillip Pickett, Yuanchi Ma, Vivek Prabhu

A model zwitterionic polysulfobetaine, poly(3-(acrylamidopropyl-dimethyl-ammonium) propyl-1-sulfonate) (pAPAPS), phase separates upon cooling with upper critical solution temperature (UCST) behavior with no added salt in deuterium oxide solutions

Li+ transport in single-ion conducting side-chain polymer electrolytes with nanoscale self-assembly of ordered ionic domains

August 22, 2022

Author(s)

Jiacheng Liu, Lingyu Yang, Phillip Pickett, Bumjun Park, Jennifer Schaefer

Li-ion batteries based on organic liquid electrolytes have been commercialized for decades. However, the flammability of the liquid electrolyte and propensity for reaction with metallic lithium anodes warrants the study of alternative electrolyte materials

Temperature Dependent Single-Chain Structure of Poly(3-(acrylamidopropyl-dimethyl-ammonium) propyl-1-sulfonate) via SANS

June 2, 2022

Author(s)

Phillip Pickett, Yuanchi Ma, Michael Lueckheide, Yimin Mao, Vivek Prabhu

Responsive polyzwitterionic materials have become important for a range of applications such as environmental remediation and targeted drug delivery. Much is known about the macroscopic phase-behaviors of such materials but how the smaller scale single

Chapter: Structure and phase behavior of polyampholytes and polyzwitterions

March 4, 2022

Author(s)

Phillip Pickett, Yuanchi Ma, Vivek Prabhu, Michael Lueckheide, Nicholas Posey

Polyelectrolytes contain many units of charged moieties, often as either anionic or cationic. However, when a polymer comprises both anionic and cationic monomers, the result is a polyampholyte. Polyzwitterions are a type of polyampholyte that contain

Development of Aqueous Size Exclusion Chromatography Conditions to Characterize Polyzwitterion-block-N-isopropyl acrylamide Copolymers

July 21, 2020

Author(s)

Phillip Pickett, Sara Orski, Vivek Prabhu

Block copolymers that exhibit both an upper critical solution temperature (UCST) and a lower critical solution temperature (LCST) are difficult to characterize due to inherent solubility difference between the two blocks. For example, accurate

Non-solvating, side-chain polymer electrolytes as lithium single-ion conductors: synthesis and ion transport characterization

October 3, 2019

Author(s)

Jiacheng Liu, Phillip D. Pickett, Bumjun Park, Sunil Upadhyay, Sara Orski, Jennifer Schaefer

Solid-state single-ion conducting polyelectrolytes have drawn considerable interest for secondary lithium batteries due to their high ion conductivities under solvent-free conditions. Specifically, poly(ethylene oxide) (PEO) based electrolytes have the
