Capacitive deionization (CDI) is an emerging technology for the facile removal of charged ionic species from aqueous solutions, and is currently being widely explored for water desalination applications. The technology is based on ion electrosorption at the surface of a pair of electrically charged electrodes, commonly composed of highly porous carbon materials.
NANOPOL project aims at the development of novel electrochemical processes for water desalination and wastewater treatment applications using nanocomposite electrodes consisted of nanocarbon materials and conductive polymers (membrane-assisted capacitive deionization, mCDI).
In this way the system’s performance can be improved (up to 50%) as compared to the common CDI.
Τhe main stages of the project concern the following:
Graphene, carbon nanotubes, carbon nanofibres and other 2-dimensional materials will be utilized.
Polymeric materials of interest are polypyrrole and polyaniline, as well as their modified nanostructures for compatibility enhancement.
Other polymers can be proposed as alternatives to enhance the anionic or cationic character of the membranes.
Conductive Polymers (PANI)
Ion Exchange Membranes
