RAMAN-SPECTROSCOPIC STUDIES OF POLYANILINE PROTONATION WITH BIS(2-ETHYLHEXYL) HYDROGEN PHOSPHATE

Protonation of polyaniline with bis(2-ethylhexyl) hydrogen phosphate l eads to its plastification. Plasticized polyaniline can be, in turn, t hermally processed, which is very important from a technological point of view. Using W-Vis-NIR and Raman spectroscopies we have demonstrate d that plasticized polyaniline is effectively protonated with the este r. Raman studies, using different excitation lines (from blue (457.9 n m) to near-infrared (1064 nm)), of polyaniline protonated with bis(2-e thylhexyl) hydrogen phosphate are presented.
