Free-standing graphene oxide/oxidized carbon nanotube films with mixed proton and electron conductor properties†
Abstract
Herein, a hybrid of graphene oxide and oxidized single-wall carbon nanotube (GO/Ox-SWCNT) free-standing film showing efficient mixed proton and electron conducting (MPEC) properties is demonstrated. The obtained proton and electronic conductivities are 5.24 × 10−3 and 1.35 × 10−3 S cm−1, respectively. The ease of the GO/Ox-SWCNT free-standing film synthesis process along with the excellent MPEC performance endow the films with a wide range of applications as solid electrolyte membranes.
