Soluble polyaniline has huge application potential and the future market needs to be further developed.

polyaniline (pani) is a type of long-chain conjugated polymer whose main chain consists of two units: p-phenylenediamine and quinonediimide. due to chain rigidity and strong inter-chain interactions, polyaniline has extremely poor solubility and is insoluble in water and most organic solvents, so its application is subject to certain limitations. in response to the solubility problem…
