Seth Darling

Seth B. Darling is the Chief Science & Technology Officer of the Advanced Energy Technologies Directorate at Argonne National Laboratory. He previously served as director of the Center for Molecular Engineering, a research and development organization partnered with the University of Chicago focusing on advanced materials for cleaning water, quantum information science, and polymer science. Darling is also a senior scientist at both the U.S. Department of Energy’s (DOE) Argonne National Laboratory and the University of Chicago’s Pritzker School of Molecular Engineering. He also directs the Advanced Materials for Energy-Water Systems (AMEWS) Center, a DOE Energy Frontier Research Center formed in 2018.

Darling has made contributions to the development of new materials for energy and water, including hybrid materials for polymer and perovskite solar cells and membrane materials for water filtration. He has co-created material synthesis techniques that are used commercially, including sequential infiltration synthesis (SIS), which is used to create coatings for semiconductor fabrication, optical surfaces, and reusable oil sorbents.

Career and education

Darling holds a PhD in physical chemistry from the University of Chicago and a bachelor’s degree in chemistry and astronomy from Haverford College. He completed his postdoctoral studies at Argonne as a Glenn Seaborg Fellow before joining its Center for Nanoscale Materials as a staff scientist. Darling was later promoted to director of the Institute for Molecular Engineering at Argonne, later renamed the Center for Molecular Engineering. In 2018, he became a senior scientist and was named director of the AMEWS Center.

Darling previously was the chief technical officer of Visual Molecules LLC, a position he held from 2008 until 2017.

Major research contributions

Darling's research focuses on developing and studying advanced materials for applications in water treatment and other technological separations. Specifically, his group has developed coatings that offer both passive (adsorption prevention) and active (catalytic degradation) properties to mitigate membrane fouling, photothermal materials for wastewater treatment (a form of solar thermal energy), and sorbents for selective removal of contaminants.

Darling has analyzed the behavior, commercial viability, scalability, and ecological impacts of photovoltaic technologies. This work reveals fundamental mechanisms of their operation and provides guidance on which solar energy technologies are sustainable and economical. Much of this work focused on the structure and properties of organic and hybrid materials. This includes polymer solar cells and perovskite solar cells.

Darling co-invented sequential infiltration synthesis (SIS) with Jeffrey Elam. SIS is a material synthesis technique derived from atomic layer deposition (ALD). While ALD alternates chemical vapors to grow materials one atomic layer at a time, in SIS the vapor is diffused into the polymer rather than on top of it. SIS has been used to create coatings for semiconductor fabrication and has applications in nanolithography (recognized with an R&D100 award in 2014), optical coatings, advanced sorbents, and membranes. SIS was also used to in the development of the Oleo Sponge to engineer a reusable oleophilic material that grabs oil molecules from water to mitigate oil spills.

Darling studied the directed self-assembly of polymers and polymer/nanoparticle hybrid systems. He’s investigated ways to tune the nanostructures that form when block copolymers self-assemble, in order to create useful materials for nanotechnologies and other applications. His most cited paper reviews methods to control the self-assembly of block copolymers and their application in microelectronics and other technologies.
