Polypyrrole micro/nanostructure prepared using azo dyes with different substituents
This contribution deals with simple way of polypyrrole structure modification.Using azo dyes in polymerization reaction as soft-template with similar molecular structure but different type and distribution of substitution groups lead to formation of one-dimensional and newly also three-dimensional polypyrrole micro/nanostructures.These structures are characteristic with geometrical symmetry and uniformity.Geometry of prepared structures was studied by scanning electron microscopy (SEM) and by methods of image analysis;nanotubes are hundreds of nm in diameter and units of μm in length,new tree-dimensional structures have units of tm in diameter.Infrared spectra (ATR-FTIR) confirmed that azo dyes work only as intermediate supporting structures without reaction with polypyrrole.
