1. A method of improving a heat transfer coefficient between an interior and an exterior of a fluid conduit, the method comprising acts of:
applying a surface treatment to an internal surface of the fluid conduit to form a treated surface,
wherein the surface treatment, after forming the treated surface on the internal surface of the fluid conduit, has a thickness of less than 1,000 nm,
wherein the surface treatment includes a chemical structure of X—R—B, wherein X is a functional component, R is a branched or unbranched hydrocarbon, alkoxy, amine, or ether chain, and B is capable of at least one of hydrogen bonding and covalently linking with the internal surface of the fluid conduit to form the treated surface, and
wherein the heat transfer coefficient for the fluid conduit having the treated surface is increased as compared to the heat transfer coefficient of the fluid conduit prior to the act of applying the surface treatment to the internal surface.
