Plasma surface engineering technologies recently present an advance in specific surface functionalization of polymer materials, such as the plasma treatment by a reactive or inert gas and the synthesis of plasma polymer coatings from a precursor. Maskless plasma nanotexturing of polymer substrates leads to the formation of various functional nanotextures exemplified by flexible nanowires, rigid nanopillars, slender nanohairs, nanocones and large nanobundles, etc. Plasma polymerization is an efficient one-step process to fabricate new surfaces with controlled amounts of specific chemical functionality at the outer surface of material. Plasma technologies also are flexibly utilized to endow specific biomimetic functionalities on polymer surfaces.
