Résumé : |
The influence of polyaniline forms on the rate and depth of curing of epoxy oligomers was determined. It is established that the use of the emeraldine form of polyaniline as a modifying agent of an amine hardener leads to the acceleration of the curing process, unlike the pernigraniline form. Studying the changes of the electronic absorption spectrum of the modified amine hardener shows the transition of the emeraldine form of polyaniline in the pernigraniline form over time. |
