Elaboration and characterization of carboxylic acid-functionalized polypyrrole films

摘要: Abstract Conducting polymers such as polypyrrole and its derivatives are highly attractive for a number of applications including biology, sensing molecular electronics. For these purposes, poly(N-carboxyalkylpyrroles) interest since they contain terminal carboxyl group that can be easily modified with biological or chemical moieties. In the present study, pyrrole monomers were by grafting, on N-position monomer, an alkyl chain, whose length varied from 1 to 10 carbons, terminated group. The substitution significantly decreased solubility but it was although possible solubilize them in acetonitrile. So, anodic oxidation N-substituted pyrroles performed acetonitrile leading electrodeposition substituted films. morphological features (topography, thickness, roughness) determined compared ones poly(N-alkylpyrroles) having same chain length. morphology polymer films shown strongly dependent non-substituted exhibited granular structure when had fibrillar structure. also impacts wettability because increase led hydrophobicity poly(N-carboxyalkylpyrroles).
