Anchoring Ionic Polymers into COF to Develop Conducting Ionic-Sponges for Charge Storage
Abstract
We will anchor ionic polymers (iPoly), known for high electronic conductivity, into the cationic-anionic COFs (iCOF) precoded with charge sites. Major design advantage- the iPoly is anchored to the COF via stronger electrostatic interactions, and each charged site on the COF wall can interact with multiple ionic polymer chains. Thus we can achieve high loading. The electronic conductivity of the iPoly will be transferred to the COF, making it communicate better with the current collector when used as an electrode. Compared to neutral polymer chains, these iPoly have the intrinsic ability to attract and store ions. Thus the entire framework of iPoly+COF will retain the inherent ionic-sponge character with high electronic conductivity. No dead weight needs to be carried. The approach is extremely versatile and can improve the windfall in charge storage.
