| Abstract: |
| In this study， polyvinyl alcohol （PVA） and cellulose nanocrystals （CNCs） were blended to form a network structure， and graphene oxide （GO） and polypyrrole （PPy） were introduced. Py was uniformly deposited on the surface of the composites by in-situ polymerization and composite aerogels were prepared by freeze-thaw cycle and freeze drying method. The Go in the composite was reduced to reduced graphene oxide （RGO） with reducing agent， and the CNCs/PVA/RGO/PPy composite aerogel with good electrical conductivity was prepared. Through the characterization and analysis of structure and electrochemical performance， the results showed that the composite aerogel has good porous network structure and excellent electrochemical performance （the specific capacity was about 352 F/g when the current density was 0.25 mA/cm2）. The composite has a good application prospect in the field of electrode materials. |
