Bio-Inspired Borate Cross-Linking in Ultra-Stiff Graphene Oxide Thin Films

Authors


Abstract

Adjacent graphene oxide nanosheets in a thin-film structure have been covalently cross-linked in a fashion similar to the cell walls of higher-order plants. The resulting ultra-stiff structure exhibits a maximum storage modulus of 127 GPa that can be tuned by varying borate concentration.
