Abstract

Poly (methyl methacrylate)/single walled carbon nanotube (PMMA/SWNT) composites were polymerized in the presence of carbon nanotubes via three methods: heat, uv radiation and ionizing radiation (gamma). Samples were solvent processed and cast into films. Thin films with varying degrees of transparency resulted from these composites. Differential Scanning Calorimetry (DSC) characterized glass transition temperatures. Ultraviolet-visible spectroscopy (UV-VIS) quantified the transparency of composites. The dielectric constant (ε') was obtained from Dielectric Analysis (DEA) and correlated to the refractive index values using Maxwell's Relationship. Scanning Electron Microscopy (SEM) provided images of the polymer- nanotube composite.
