Multifunctional group sulfobutyl ether β-cyclodextrin polymer treated CNT as the cathode for enhanced performance in asymmetric capacitive deionization

In order to enhance the desalting performance of electrode in the capacitive deionization process (CDI), a novel sulfobutyl ether β-cyclodextrin polymer with multi-sulfonic groups and multi-hydroxyl groups (SBE-β-CDP) was successfully synthesized and attached on the surface of carbon nanotubes (CNT) by non-covalent bond. The as-prepared [email protected]β-CDP electrode possesses significantly improved capacitance property and hydrophilicity...
