Tailoring the Properties of Carbon Nanotubes by Filling and Irradiation

Presented by:Professor Susan Sinnott, University of FloridaAbstract:Classical molecular dynamics simulations with many-body empirical potentials are used to study the chemical modification of carbon nanotube based materials. Chemical modification of nanotubes is important for tailoring their properties and ultimately controlling their adhesion to polymers in composites. The simulations focus on the effects of filling nanotubes with gases and clusters on their mechanical and thermal properties. Additionally, they show that irradiation of carbon nanotube structures, bundles, and composites with electron or polyatomic ion beams can substantially modify the properties of the systems without destroying their fundamental structure. Thus the simulations show how the inherently desirable properties of carbon nanotubes can be tailored through filling and/or irradiation.Refreshments will be served at 2:30p.m.**ALL FIRST-YEAR MATERIALS SCIENCE GRADUATE STUDENTS ARE REQUIRED TO ATTEND**
