Description
| - The reaction between two non-conducting compounds, aniline and silver nitrate, yields a composite of two conducting products, PANI and silver. While the oxidation of aniline with silver nitrate is slow and takes over several months, the addition of a small amount of p-phenylenediamine, 1 mol % relative to aniline, shortens the reaction time to a few hours and, with higher concentrations of p-phenylenediamine, even to tens of minutes. The chemistry of individual oxidation pathways is discussed. p-Phenylenediamine alone can similarly be oxidized with silver nitrate to poly(p-phenylenediamine) composite with silver. Silver is present in the composites both as nanoparticles of 50 nm size and as larger objects. The semiconductor type of conductivity in polymers and the metallic type of conductivity in silver may compensate to yield composites with conductivity nearly independent of temperature over a broad temperature range.
