Wood based ionic diode

Wood and its derivatives are highly attractive materials, not only due to their sustainability, low cost, and biodegradability, but also because of their intrinsic porous and hierarchical structure, excellent mechanical properties, and versatile surface chemistry. In this work, we present an ionic diode based on bipolar membranes fabricated from two oppositely charged wood membranes. The abundant functional groups in wood cellulose allow for facile tuning of surface charge density through chemical modification. We will focus on investigate of the relationships between the charge densities, wood structure and ionic diode performance.
