Functionalization of SWNT buckypapers through electron-beam irradiation Conference Paper uri icon


  • This paper presents a method to improve both mechanical and electrical properties of single-walled carbon nanotube (SWNT) buckypaper materials through electron-beam irradiations. Free-standing SWNT buckypaper provides a means to assemble individual carbon nanotubes into macroscopic articles so that the nanotubes can be potentially utilized for applications in areas such as electronic devices, biomaterials, nanocomposites and energy storage. However, the weak interactions among SWNTs make pristine SWNT sheets low strength with high electrical contact resistance and seriously reduce the film conductance. In this research, SWNT buckypaper were irradiated under a 2Mev electron beam and then characterized by Raman spectroscopy, TEM, DMA and electrical resistance measurements. The results indicate that the properties of irradiated buckypaper papers depend on the irradiation dosages. The tensile strength and modulus of the buckypaper materials can be enhanced by more than 8 fold and 2 fold, respectively.
