The polyaniline (PANI) base was ball-milled with silver nitrate in the solid state. The emeraldine form of PANI was oxidized to pernigraniline, and the silver nitrate was reduced to metallic silver. The changes occurring in the structure of PANI are discussed on the basis of Fourier transform IR and Raman spectroscopies. Raman spectra revealed the formation of pernigraniline salt.

Polyanilinová báze byla mletá s dusičnenm stříbrným v pevném stavu. Emeraldinová forma polyanilinu se oxidovala na pernigranilin a dusičnan stříbrný se redukoval na kovové stříbro. Změny pozorované ve struktuře polyanilinu jsou diskutovány na základě infračervených a Ramanových spekter. Ramanova spektra odhalila tvorbu pernigranilinové soli.
