Li Leads Research on Nano Ceramic Films

Assistant Professor Teng Li (mechanical engineering) has recently received a three-year, $380,000 National Science Foundation (NSF) collaborative research grant, for his research titled, "Deciphering the Reliability of Nano Ceramic Films on Polymer Substrates: A Mechanistic Study." Li is co-principle investigator along with collaborator Assistant Professor Jun Lou of Rice University.

The collaborative team plans on building a research framework (from analytic modeling, simulations to in situ experiments) in order to explore the underpinning mechanisms that govern the mechanical reliability of nano ceramic films on polymer substrates, important because functional such films are becoming fundamental to emerging technologies, such as flexible electronics and next generation bioactive implants.

"The research will result in broad social impacts," says Li. "The widespread use of flexible electronics, such as paper-like displays, flexible organic light-emitting diodes, printable thin-film solar cells, and skin-like smart prostheses can address important societal needs for easy access to information, renewable energy, a sustainable environment and revolutionary concepts for therapy."

The expected outcome of the research is to ascertain knowledge vital to the understanding and the further improvement of the mechanical reliability of the nano ceramic films, a crucial but largely unexplored issue in its applications in flexible electronics and next generation bioactive implants.

This NSF collaborative grant is in line with Li's research focus on the mechanical challenges and solutions of flexible electronics. Earlier this year, Li also received a three-year, $309,000 NSF GOALI grant to investigate the mechanics of permeation barriers in flexible electronics.
