Chemical effects of ion implantation in polyaniline

The chemical changes of polyaniline resulted from implantation of H, B, P, F, BF2, or Ar ions have been studied. From ESCA studies it is concluded that the number of nitrogen atoms in polyaniline decreases with increasing ion dose, while the number of oxygen atoms in the ion implanted layer of polyaniline increases. ESR (electron spin resonance) spectra show that the radical concentration in polyaniline increases with the ion dose. From FTIR analysis, two different kinds of chemical changes in the irradiated polyaniline are found, one from implanting H, F, or BF2 ions and the other from implanting B, P, or Ar ions. ((orig.))
