Application

This polyaniline product is crosslinked by a dopant molecule - phytic acid, to form a highly porous 3D nanostructure. It is intrinsically conductive and has large open channels advantageous for sensing and energy storage applications. These open micro/nano channels promote the transport of electrons and facilitates the diffusion of ions, and small molecules. Additionally, pyrolyzing this polyaniline could yield highly porous 3D cross-linked graphitic carbon for a broad range of applications.
High surface area conducting polyaniline can be used as the active semiconductor layer in Organic Field-Effect Transistors (OFET) devices. In OPV devices, high surface area conducting polyaniline can be incorporated as a conductive additive or component. By adding the material to the active layer materials or the charge transport layers, it can enhance the electrical conductivity and facilitate charge extraction, contributing to improved device performance.
