with Supercapacitive Properties"

Portable electronic devices are one of the most widely-adopted technologies of the 21st century. The current technology that is being used to store and distribute energy needs to develop at a pace equal to that of the demand for smaller and smaller electronics. Batteries have served as a faithful storage medium for decades past and will continue to power much of the world around us for decades to come, but applications are beginning to emerge which challenge the limits of energy portability. For these, there is a need for research concerning an alternative form of energy storage such as capacitors. Capacitors function in a way that is distinctly different from batteries. Where a battery contains electrical energy in the form of chemical potential energy, a capacitor stores electrical energy in an electric field which is produced in proportion to the surface area of the material of which it is composed. New technology in the form of advanced electrical circuitry has opened the field of capacitors to the possibility of being used as primary energy storage, leading to a renewed interest in the development of supercapacitors with very high surface areas capable of storing much larger amounts of charge. This, in turn, has led to a need for better techniques to produce new materials that have supercapacitive properties. Electrochemical polymerization harnesses the powerful technique of electrochemistry to facilitate the tunable synthesis of conjugated microporous polymers. These polymers, by virtue of their molecularly porous structure, offer surface areas that give them the potential to serve as supercapacitors. REFERENCES: (1) MacInnes, D., Druy, M.A., Nigrey, P.
