Abstract
This paper prepared the composite aerogel by adding graphene oxide (GO) and polypyrrole (PPy) to the cellulose nanofiber suspension. Then GO was reduced to RGO (reduced graphene oxide) with reducing agent, and CNFs/RGO/PPy composite aerogel with excellent conductivity was prepared. Scanning electron microscope (SEM) was adopted to analyze the structure and morphology of CNFs/RGO/PPy aerogel. Cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy (EIS) were employed to analyze its electrochemical properties. The results showed that the best structure and electrochemical effect could be obtained when the ratio of CNFs/RGO/PPy was 6:2:3. At the current density of 0.25 mA cm−2, CNFs/RGO/PPy composite aerogel had higher electrochemical performance, and the specific capacitance was 330 F g−1. As an energy storage material, the composite has excellent potential in electrode materials.
