  2. 1. Properties and applications of materials based on graphite oxide

    Author : Andreas Nordenström; Aleksandr V. Talyzin; Thomas Wågberg; Andrey Turchanin; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Graphene; Graphite Oxide; Graphene Oxide; Swelling; Phase Transition; Intercalation; Activated Graphene; Activated Carbon; Supercapacitors; Neutron Reflectometry;

    Abstract : Graphite oxide (GO) is a hydrophilic, layered material prepared by oxidation of graphite. In the first part of this thesis, we studied materials produced from GO by intercalation and functionalization. The second part of the thesis was focused on supercapacitor applications of high surface area carbons prepared from GO using chemical activation. READ MORE
