RUSTON, La. Dr. Yuri Lvov, professor of chemistry and T.C. Pipes endowed chair in micro and nanosystems at Louisiana Tech University, recently led a symposium at the 241st Conference of the American Chemical Society (ACS), discussing his application of a more eco-friendly and cost-effective nano-material that can be used to significantly improve the properties of plastics, paints and other synthetic composites.
The symposium featured Lvov's presentation on the use of clay "nanotubes" created from dirt and soils found in a number of places on earth to strengthen plastics, paints, epoxies, rubber and others materials. The nanotubes can also be infused with different chemical agents, providing them with anticorrosion or antimicrobial properties.
The ACS event, recently held in Anaheim, California, is the world's largest professional chemical conference with over 12,000 participants in attendance. Lvov served as chief organizer and chairman of the Polymer-Clay Nanocomposites Symposium.
"It was an honor to organize the Polymer-Clay Nanocomposites symposium at this meeting," said Lvov. "A significant amount of time was spent contacting participants, shaping the program, selecting speakers, organizing a symposium dinner, and finding financial support for the program. We were chosen to lead this symposium because of our pioneering of the use of this new type of clay in polymer composite."
Lvov was one of the first scientists in the world to recognize the potential of naturally occurring clay nanotubes. Unlike carbon nanotubes, the clay nanotubes are available by the ton, are considerably cheaper, and are nontoxic. They also allow scientists to modify the properties to the resulting composites, in beneficial ways.
Lvov's symposium presentation detailed the technology of polymer doping with different types of dispersed clay nanoparticles. The clay, after chemical processing, can be dispersed into tiny particles of a f
