Aging of Water-Soluble Formulations for Inkjet Printing of Functional Layers Based on Polyaniline

Аннотация

The process of aging of water-soluble formulation based on polyaniline with poly(2-acrylamido-2-methyl-1-propanesulfonic acid) complex was studied by controlling the value of pH, optical absorption spectra, the rheological properties of its solutions, and the specific conductivity of the films cast from the studied solutions. It was shown that solutions of water-soluble compositions based on polyaniline acquire stable characteristics after 6-week storage; these characteristics are retained for at least 6 months. They can be used for technological processes (inkjet printing, spin coating, dip-coating) for obtaining functional layers for optoelectronics.
