TI  - Analytical characterization of poly(pyrrole-3-carboxylic acid) films 
      electrosynthesised on Pt, Ti and Ti/Al/V substrates.

AB  - With the aim of developing a polymeric multilayer film for application in 
      advanced biomaterials, as a first step poly(pyrrole-3-carboxylic acid) films 
      (abbreviated as PPy-3-carbox) were electropolymerised from pyrrole-3-carboxylic 
      acid solutions by cyclic voltammetry and chronoamperometry on platinum, titanium 
      and Ti90Al6V4 substrates and characterised both electrochemically (cyclic 
      voltammetry) and spectroscopically (X-Ray Photoelectron Spectroscopy, XPS). 
      Electrochemical experiments showed that the potential range adopted for 
      electropolymerization affects the polymer electroactivity, by analogy with 
      unsubstituted polypyrrole. The combination of conventional and chemical 
      derivation-XPS provided information on PPy-3-carbox surface structure, showing no 
      significant difference between films grown on different substrates and an 
      increase of the COOH groups amount (one group over three pyrrole rings, as an 
      average) with respect to unsubstituted polypyrrole (PPy), as expected. Finally, a 
      preliminary Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) 
      investigation was performed in order to get further information on the polymer 
      structure and electroactivity.
