# Jodie Lutkenhaus

Jodie L. Lutkenhaus is a Professor of Chemical Engineering at Texas A&M University who develops redox active polymers for energy storage and smart coatings. In 2019 Lutkenhaus and Karen L. Wooley demonstrated the world's first biodegradable peptide battery. Lutkenhaus is a World Economic Forum Young Scientist.

## Early life and education

Lutkenhaus was inspired to study engineering by her mother and father, who studied chemistry and physics respectively. She studied chemical engineering at the University of Texas at Austin and graduated in 2002. She moved to Massachusetts Institute of Technology. After obtaining her doctoral degree there in 2007 under the supervision of Paula T. Hammond, Lutkenhaus moved to the University of Massachusetts Amherst, and then in 2008 joined the faculty of Yale University.

## Research and career

Lutkenhaus joined the faculty at Texas A&M University in 2010, and was promoted to Associate Professor in 2015. She develops new materials for energy storage and smart coatings, including polyelectrolytes and redox active polymers. She aspires to develop soft and flexible power supplies for wearable electronics that are durable, sustainable and efficient.
A challenge with using polymers in batteries is that they are typically poor at storing and exchanging electrons. Lutkenhaus has demonstrated that organic radical polymers are electrochemically active, allowing for fast charge transfer during redox reactions. If used in portable electronic devices, organic radical polymers could enable fast charging. Lutkenhaus has characterised the speed of charge transfer in these systems using an electrochemical quartz crystal microbalance. She hopes that future batteries will be metal-free, organic and recyclable. (At present, only 5% of lithium-ion batteries are recycled.) Lutkenhaus and Wooley demonstrated that glutamic acid could be used to make batteries—the first fully biodegradable protein battery. The peptides contain redox-active compounds, the stable radical Tempo on the cathode and bipyridine viologen on the anodes.
Lutkenhaus has studied how polymer films behave when deposited in confined spaces. She is developing two-dimensional transition metal-carbon nanosheets (MXenes), sheet-like structures made from layered ceramics that can include a range of different composites and functional groups. She is also investigating how chemical structure and molecular packing influence these materials' electronic properties. She has shown that MXene-polyelectrolyte devices can be used to sense humidity and pressure, as water facilitates the relaxation of charged molecular assemblies by reducing Coulombic attraction.
