Graduate Theses & Non-Theses
Conductive polymer nanocomposites are a type of particle reinforced plastic composite where the doping material is electrically conductive. The diverse properties of an engineered composite material allow for the material properties to be fine-tuned for the specific application. This research focuses on using carbon allotropes, such as two-dimensional graphene and one-dimensional carbon nanotubes, to achieve direct current electrical conductivity through a polymer fiber. Melt electrospinning is the process used for creating the micrometer scale fibers by melting thermoplastic materials. High electrostatic fields apply a force to the polymer melt and a single fiber is drawn out. The resistivity of the …

This work presents a probabilistic approach to model the electrical transport properties of carbon nanotube composite materials. A pseudo-random generation method is presented with the ability to generate 3-D samples with a variety of different configurations. Periodic boundary conditions are employed in the directions perpendicular to transport to minimize edge effects. Simulations produce values for drift velocity, carrier mobility, and conductivity in samples that account for geometrical features resembling those found in the lab. All results show an excellent agreement to the well-known power law characteristic of percolation processes, which is used to compare across simulations. The effect of sample …
