Molecular Dynamics Simulations of Composite Polymer Membranes

In the past decade, Protic Ionic Liquids (PILs) have spurred interest in them for their potential use in fuel cells batteries, and super-capacitors, dye-sensitized solar cells etc. Recently, the use of PIL as a dopant lead to a remarkable enhancement in electrochemical properties of PIL doped polymer composite membrane materials. A molecular probing of PIL doped composite membrane can provide new physical insights to develop more efficient anhydrous electrolytes for emerging energy technologies (fuel cells, batteries, and super-capacitors etc.)
