Abstract
Methods for coating the interior surface of tubular structures having high aspect ratios and tubular structures produced by such methods. The interior surface of the tubular structure is coated by inducing a magnetic field having a given magnitude around a circumference along a length of the tubular structure, applying a bias at a given voltage to the tubular structure, and exposing the interior surface to a precursor material to deposit the precursor material onto the interior surface of the tubular structure.
