Functionalization of graphene oxide surface by conjugation with glucosamine and analysis of interactions occurring in nanoceramic-graphene heterostructures
Abstract
The paper describes the chemical modification of the graphene oxide (GO) surface with glucosamine, which wasconjugated to GO via a carbodiimide-mediated amidation-type reaction. The efficiency of the reaction wasconfirmed by FT-IR and Raman spectroscopy and elemental analysis. The elaborated functionalization significantlyreduces the agglomeration of graphene oxide platelets. The interactions at the interface of GO and twotypes of ceramic nanoparticles (ZrO2 and Al2O3 with particle sizes of 58 nm and 158 nm, respectively) wereexamined by zeta potential measurements at different pH values. The viscosity of ZrO2 suspensions (35 vol% ofsolid loading) at 1.5 sက00 1 increases from 24.8 Pas to 170.7 Pas and 142.7 Pas with the addition of GO and f-GO,respectively. The interfaces at ceramic-graphene heterostructures obtained by slip casting method have beenanalyzed by SEM. The investigations revealed the presence of multilayer graphene oxide and flexible single-layerf-GO within the ceramic matrix.
