Fabrication of functional polypyrrole (PolyPyr)-nanotubes using anodized aluminium oxide (AAO) template membranes. Compromising between effectiveness and mildness of template dissolution conditions for a safe release of PolyPyr-nanotubes

Functional acidic (COOH) pyrrole (Pyr)-containing oxidizable monomers can be template-polymerized using hard nanoporous anodized aluminium oxide (AAO) membranes in liquid phase polymerization (LPP) conditions. Accordingly, the safe and effective release of resulting functional polyCOOH-polypyrrole (polyPyr)-nanotubes from template membranes must be operated in controlled acidic, instead of commonly used Martin-like basic conditions (membrane digestion).
