15N CPMAS NMR study of the structure of polyaniline
Source abstract
Abstract
The structure and properties of polyaniline are investigated using 15N cross polarization magic angle spinning (CPMAS) solid state NMR spectroscopy. The high resolution spectra obtained demonstrate the potential of the method for studying the structures of other nitrogen containing heterocyclic polymers.

37. The NMR experiments were performed on a Bruker CXP 100 spectrometer working at 90.02 MHz for protons using a 5 mm Doty MAS probe [34]. The rotation frequencies of the 5 min o.d. rotors were between 2.5 and 3.5 kHz; thus rotational sideband free spectra could be obtained. All spectra were referenced to external15NH4Cl.

39. The PANI‐samples were prepared with equipment described previously [36] as follows. Aniline‐15N was electropolymerized galvanostatically at a current density of 1 mA/cm2at a concentration of 0.1 moll−1using HClO4/water mixtures as solvent. Samples 1 and 2 were prepared at a HClO4concentration of 1 moll−1 sample 3 at a concentration of 3 mol 1−1. The precipitates on the electrodes were washed with acetonitrile and dried in vacuo. Then the samples were discharged at a potential of – 0.4 V vs. Ag/AgCl in acetonitrile containing 0.5 moll−1LiClO4as supporting electrolyte. Sample 2 was thoroughly washed with water and then with acetonitrile in contrast to sample 1 which was washed only superficially. Finally all samples were dried in vacuo.
