title: Nanostructured conducting polymers as intelligent implant surface: fabricated on biomedical titanium with a potential-induced reversible switch in wettability.
abstract: Conducting polypyrrole (PPy) nanotube arrays, nanotube networks and irregular films are deposited on biomedical titanium. By in situ application of weak periodic potentials, the nanostructured conducting polymers undergo a reversible switch in wettability, which is a redox process of dopant molecules (as hydrophilic groups) immobilized and de-immobilized on the surface of the conducting polymers.
