This Masters Thesis presents a theoretical model of coating growth resulting from a procedure to coat nanofibers and core-clad nanostructures. These nanofibers and nanostructures are coated with thin film materials using plasma enhanced physical vapor deposition (PEPVD). In the experimental effort, electrospun polymer nanofibers are coated with metallic materials under varying operating conditions to observe changes in the coating morphology. This paper investigates non-uniform axial growth with uniform radial growth. The interrelationships among processing factors for the transport and deposition of the coating material are investigated here. This includes both the salient physical and chemical phenomena. This parametric study results in an evolution equation describing coating growth. This equation is first solved using a boundary perturbation method to determine the coating morphology as a function of operating conditions. This results in a solution that describes uniform coating growth. The weakly nonlinear solution is then determined and describes non-uniform growth in the axial direction. The nonlinear evolution equation is then analyzed using linearization methods and a solution of separable form. Lastly, the evolution equation is parameterized using an arc-length technique. This results in a pair of differential equations that are solved numerically. Also, a parametric study is presented.
