Morgan Stefik obtained his degree in Materials Engineering from Cal Poly SLO, USA in the year 2005. He has completed his Doctoral studies in Materials Science at Cornell University under the supervision of Prof. U Wiesner and Prof. F J DiSalvo in the year 2010. After two years of Post-doctoral research at Ecole Polytechnique Federale de Lausanne with Prof. M Gratzel, he joined the University of South Carolina in the year 2013 as an Assistant Professor in the Department of Chemistry and Biochemistry. He is the Founding Director of the NSF which supported South Carolina SAXS Collaborative. His research focuses on nano- materials chemistry with emphasis on self-assembly techniques and atomic layer deposition.
The ability to tune nanoscale features in traditional materials can enable new properties or enhanced performance in technologies ranging from optoelectronics to super-capacitors and solar devices. Our lab takes inspiration from the promise of nanomaterials chemistry to advance the capabilities of devices for both energy conversion and storage. One of our core strategies is the design of novel block copolymer self-assembly systems that enable new levels of precision. In this talk, I will focus on recent developments where new amphiphilic block copolymers are synthesized by controlled radical techniques to enable advanced solution processing of inorganic nanostructures. Solution processing is highly scalable, but more subtly is also highly tunable to result in markedly different nanostructures. With one example, we apply thermodynamic concepts to direct the entrapment of block copolymer micelles for self-assembly with precision control. The resulting tunable isomorphic architectures have widespread applications to advance (photo) electrochemical devices.
