Secondary amines are added to emeraldine base (EB)/N-methyl-2-pyrrolidinone (NMP) solutions to stabilize the EB solution. However, amines can interact with the EB molecule either by physical interaction, such as with the hydrogen bond (H-bond), or by chemical reaction. Several amines with different...
