CHEMICAL SYNTHESIS AND CHARACTERIZATION OF POLYANILINE DERIVATIVES: SUBSTITUENT EFFECT ON SOLUBILITY AND CONDUCTIVITY

Polyanilines have different macroscopic properties according to the substituent incorporated into their monomers. Being conducting polymers, one of these properties is conductivity, which may increase or decrease depending on the substituent and its position in the chain. This work is focused on the...
