MSE PRO 1g Amine Functionalized Graphene Oxide Powder
SKU: PO0708
Description of Amine Functionalized Graphene Oxide Powder
The amine functional groups on the graphene oxide powder improves its dispersion in polymer matrices (such as epoxy resins, polyester resins, poliols among others). The key to improving the mechanical properties of the composites is to achieve an homogeneous dispersion of the filler in the polymer matrix. It has been proven in the literature that the amine functionalization of graphene oxide powder is an successful approach to achieve it.

FAQs
A: During the functionalization process, some of the oxygen moities are reduced, and at the same time alkyl chains are added to the structure. Due to this changes in the composition the dispersability in water decreases and the dispersions are not stable. In order to dispersed it in water surfactants have to be added. Also rGO can be dispersed in low concentrations in NMP, DMF or MeOH.
A: When the alkyl amine is added the interlayer distance of the material is increased what is clearly observed in the XRD spectra, where the (002) peak shifts from 9-11 to around 5-6. On the other hand, the % of N in the elemental analysis (2-4%) indicates the presence of the amine groups.
