Cellulose Nanocrystal Aerogels as Universal 3D Lightweight Substrates for Supercapacitor Materials

Adv Mater. 2015 Oct 28;27(40):6104-9. doi: 10.1002/adma.201502284. Epub 2015 Sep 2.

Abstract

Chemically cross-linked cellulose nanocrystal aerogels represent a versatile and universal substrate on which to prepare lightweight hybrid materials. In situ incorporation of polypyrrole nanofibers, polypyrrole-coated carbon nanotubes, and manganese dioxide nanoparticles in the aerogels gives flexible 3D supercapacitor devices with excellent capacitance retention, low internal resistance, and fast charge-discharge rates.

Keywords: carbon nanotubes; manganese dioxide; nanocellulose aerogels; polypyrrole; supercapacitors.
