Abstract:
We have demonstrated there is a significant intermolecular interaction between GO and KGM that results from hydrogen bonding and physical cross-linking by studying the rheological properties of a graphene oxide/konjac glucomannan (GO/KGM) solution. When the addition of GO was 5%, the storage modulus (G') and loss modulus (G″) were only improved by 0.25%. However, G' and G″ were improved by approximately 90% and 73.4%, respectively, when the GO content was increased to 7.5%. The moduli also displayed a relationship between the power function and concentration. Furthermore, the formation mechanism of GO/KGM was investigated by Raman, FT-IR, XPS and SEM. The results suggested that hydrogen bonding and physical crosslinking are generated from the abundant carboxy and hydroxyl groups of graphene oxide and the hydroxyl groups of konjac glucomannan.
