Jingwen Liao, Prof. Chengyun Ning, Guoxin Tan, Prof. Guoxin Ni and Haobo Pan Conducting Polypyrrole Nanotube Arrays as an Implant Surface: Fabricated on Biomedical Titanium with Fine-Tunability by Means of Template-Free Electrochemical Polymerization ChemPlusChem 79
Grass roots: Template-free electrochemical polymerization in phosphate buffer solution has been used to obtain grasslike polypyrrole (PPy) nanowires of low density on titanium (see figure). By introducing a prenucleation film on the titanium, conducting PPy nanotube arrays (CPNAs) of large area were fabricated. The architectures of the CPNAs can be finely tuned between cones and cylinders by changing the electrochemical parameters.
