Deep eutectic solvent assisted preparation of cellulose nanofibers and graphene composite films for supercapacitors

Abstract

Flexible cellulose nanofiber-modified graphene composite has been prepared using rice husk and graphite as the feedstocks. At first, cellulose nanofibers (CNF) has been obtained from designated rice husk by green...

Sustainable low temperature carrier gas-free growth of graphene on non-catalytic substrates

“…Graphene and graphene-like materials have become some of the most researched materials of the 21st century. 1 Their unique electrical, mechanical and optical properties have made them candidates for applications including energy conversion and storage, 2–4 photovoltaics, 5–7 electronics, 8 water purification 9 and electrolysis, 10 sensing 11–14 and bio-sensing, 15 anti-corrosion films 16 and biomedical applications. 17–19 One promising material is vertically aligned graphene (VG) which consists of graphene sheets, typically with a few layers, that have been grown or attached perpendicular to a substrate.…”
