Conductive_PANI_3_06032013

Here my first mindmapping attempt about structure-conductivity relationship for aniline-based materials.  The final conductivity of the material can be explained in terms of mobility of charge along a pi-conjugated segment and charge hopping process. These two process are affected by crystalline defects in the supramolecular structure of the material. Previous reports have shown that an increase in crystallinity have produced an increase in conductivity. Different strategies have been proposed to enhance the crystalline structure of Poly(aniline)-based materials such as using dopant agents that present ionic interactions with the backbone-chain of the polymer. These secondary interactions lead to self-organization of the molecules in films with long-range structure.
